ʻO ka Ammonium molybdate, kahi pūhui inorganic i haku ʻia me ka molybdenum, oxygen, nitrogen, a me nā mea hydrogen (i kapa ʻia ʻo ammonium tetramolybdate a i ʻole ammonium heptamolybdate), ua lōʻihi ka lōʻihi ma mua o kāna hana ma ke ʻano he reagent laboratory ma muli o kāna mau mea kemika kūʻokoʻa - ka hana catalytic maikaʻi loa, ka hiki ke hana i nā hiʻohiʻona ʻano i loko o ka monumolybdate. oxides a i ʻole molybdenum metala ma lalo o nā kūlana kikoʻī. Ua lilo ia i pōhaku kihi kemika koʻikoʻi e kākoʻo ana i nā kahua koʻikoʻi e like me ka ʻoihana hou, ka mahiʻai, ka ʻepekema waiwai, a me ka hoʻāʻo ʻana i ke kaiapuni.
1. ʻO ka mīkini kumu ma ke kahua o ka catalysis: hoʻokele i ka ikehu maʻemaʻe a me ka ʻoihana kemika maikaʻi
Ma ke kahua o ka catalysis,ammonium molybdatehiki ke manaʻo ʻia ma ke ʻano he "pohaku kumu kumu". ʻO kāna kumu nui ka hana ʻana i nā catalysts hydroprocessing (HDS catalyst for desulfurization, HDN catalyst for denitrification). I ka lawe ʻana i ka hoʻomaʻemaʻe ʻaila ma ke ʻano he laʻana, hoʻohana ʻia ka hapa nui o ka ammonium molybdate i hoʻopau ʻia i kēlā me kēia makahiki no kēia kumu:
Desulfurization hohonu a me ka denitrification: Molybdenum oxide i hana ʻia e ka decomposition o ka ammonium molybdate i hoʻouka ʻia ma luna o kahi mea lawe alumina a hui pū me ka cobalt a i ʻole nickel oxides e hana i ka precursor o ka mea hana o ka catalyst. Hiki i kēia catalyst ke hoʻoheheʻe a hoʻololi i nā sulfides organik (e like me ka thiophene) a me nā nitrides organik i loko o ka ʻaila maʻemaʻe a me kāna mau hakina (e like me ka diesel a me ka ʻaila) i loko o ka hydrogen sulfide, ammonia, a me nā hydrocarbons saturated i loko o kahi kaiapuni hydrogen kiʻekiʻe. ʻAʻole wale kēia e hoʻemi nui i ka sulfur maʻiʻo o nā wahie automotive (e hui ana i nā hoʻoponopono kūlohelohe e like me nā kūlana Euro VI), e hoʻemi i ka hoʻokuʻu ʻana o ka ua waikawa a me ka PM2.5 precursor SOx, akā hoʻomaikaʻi pū i ka paʻa o ka wahie a me ka hana engine.
Hoʻonui i nā noi: I ka koho hydrogenation kaʻina o ka lanahu liquefaction, ka aila a me ka momona hydrogenation hoʻomaʻemaʻe e hana ai i ka aila meaʻai meaʻai aiʻole biodiesel, a me nā huahana kemika like ʻole, nā catalysts e pili ana i ka ammonium molybdate e pāʻani pū kekahi i ke kuleana koʻikoʻi, e hoʻokele i ka hana kūpono a maʻemaʻe o ka huila nunui.
2. ʻO ke aliʻi maʻamau o ke kemika analytical: ka "maka gula" no ka ʻike pololei
ʻO ka "molybdenum blue method" i hoʻokumu ʻia e ka ammonium molybdate i ka kemika analytical ke kumu gula no ka ʻike nui ʻana o ka phosphate (PO ₄³ ⁻), i hana ʻia.
hoʻāʻo ʻia no hoʻokahi haneli mau makahiki:
Kuʻuna hoʻomohala kala: I loko o kahi mea ʻawaʻawa, hoʻopili nā ion phosphate me ka ammonium molybdate e hana i kahi paʻakikī phosphomolybdic acid melemele. Hiki ke hoʻemi ʻia kēia paʻakikī ma o ka hoʻohaʻahaʻa ʻana i nā mea hana e like me ka ascorbic acid a me ka stannous chloride, e hana ana i kahi kala uliuli hohonu "molybdenum blue". ʻO ka hohonu o kona waihoʻoluʻu e pili pono i ka neʻe ʻana o ka phosphate ma kahi hawewe kikoʻī (e like me 880nm).
Hoʻohana ākea: Hoʻohana nui ʻia kēia ʻano i ka nānā ʻana i ke kaiapuni (ka loiloi i ka pilikia o ka eutrophication i loko o ka wai ʻili a me ka wai phosphorus content), ka noiʻi mahiʻai (ka hoʻoholo ʻana i ka lepo i loaʻa i ka phosphorus a me ka mea momona phosphorus content), ʻoihana meaʻai (ka mālama ʻana i ka ʻike o ka phosphorus i nā mea inu a me nā mea hoʻohui), a me ka biochemistry (ka nānā ʻana o ka phosphorus inorganic a me ka phosphorus kiʻekiʻe i kona seboliterum. trace level), hana maʻalahi, a me ke kumu kūʻai haʻahaʻa. Hāʻawi ia i ke kākoʻo ʻikepili hilinaʻi no ka pale ʻana i ka maikaʻi o ka wai, ka hoʻomaʻamaʻa pololei ʻana, a me ka noiʻi ʻepekema ola.
3.Dual hana o ka hana metala a me ka metallurgy: akamai i ka pale a me ka hoʻomaʻemaʻe
Hoʻohana nui ʻia ʻo Ammonium molybdate ma ke ʻano he anodic corrosion inhibitor i ka mālama ʻana i ka wai ʻoihana (e like me ka nui o ka ea nui o ka ea hoʻoluʻu wai ʻana, boiler feedwater) a me ka mea hoʻoheheʻe ʻenekini automotive ma muli o kona ʻoluʻolu o ke kaiapuni. Hoʻopili ia ma ka ʻili o nā metala (ʻoi aku ke kila a me nā alumini alumini) e hana i kahi kiʻiʻoniʻoni passivation molybdenum e pili ana i ka molybdenum (e like me ka hao molybdate a me ka calcium molybdate), me ka pale ʻana i ka corrosion o ka substrate e ka wai, dissolved oxygen, a me nā ion corrosive (e like me ka Cl ⁻ hoʻonui i ke ola).
ʻO ke kumu o ka molybdenum metala a me nā ʻāpana: ʻo ka ammonium molybdate maʻemaʻe kiʻekiʻe kahi kumu mua no ka hana ʻana i ka pauka molybdenum metala kiʻekiʻe. ʻO ka pauka Molybdenum e kū ana i nā koi o ka pauka metallurgy hiki ke hana ʻia ma o ka mana pololei o ka calcination a me nā kaʻina hoʻohaʻahaʻa (maʻamau i ka lewa hydrogen). Hiki ke hana hou ʻia kēia mau pauka molybdenum e hana i nā mea hoʻomehana wela wela wela, nā kīʻaha ʻoihana semiconductor, nā ʻāpana molybdenum kiʻekiʻe (e like me ka molybdenum titanium zirconium alloys i hoʻohana ʻia no nā ʻāpana wela wela), a me nā huahana kiʻekiʻe e like me ka sputtering targets.
4. Agriculture: He 'Celebration of Life' no nā 'Elemu Huli
ʻO ka Molybdenum kekahi o nā mea pono no nā mea kanu a he mea koʻikoʻi ia no ka hana o ka nitrogenase a me ka nitrate reductase.
Molybdenum fertilizer core: ʻO Ammonium molybdate (ʻoi aku ka ammonium tetramolybdate) ʻo ia ka mea nui no ka hana ʻana i nā mea kanu molybdenum maikaʻi ma muli o kona ʻano wai maikaʻi a me ka bioavailability. Hoʻopili pololei ʻia a i ʻole ʻia e like me ka foliar fertilizer hiki ke pale a hoʻoponopono i nā hōʻailona deficiency molybdenum (e like me ka melemele ʻana o ka lau, deformities - "maʻi huelo hui ʻana", ka pale ʻana i ka ulu ʻana) i nā mea kanu leguminous (e like me ka soybeans a me ka alfalfa e hilinaʻi nei i ka rhizobia no ka hoʻoponopono ʻana i nā mea kanu) a me nā hua puaʻa cruciferous.
Hoʻonui i ka hua a me ka hoʻomaikaʻi ʻana i ka maikaʻi: ʻO ka hoʻonui ʻana i ka ammonium molybdate fertilizer hiki ke hoʻoikaika nui i ka mea kanu nitrogen metabolism pono, hoʻomaikaʻi i ka synthesis protein, hoʻoikaika i ke kūpaʻa kaumaha, a hoʻomaikaʻi i ka hua a me ka maikaʻi o nā mea kanu, he mea nui ia no ka hōʻoia ʻana i ka palekana o ka meaʻai a me ka hoʻomohala ʻana i ka mahiʻai.
5. Materials Science: Ke 'Kumu o ka Naauao' no na mea hana
Hāʻawi ka hiki ke hoʻololi kemika o ka ammonium molybdate i kahi ala koʻikoʻi no ka synthesis o nā mea holomua:
ʻO nā seramika hana a me nā mea i hoʻopaʻa mua ʻia: ma o ka sol gel, spray drying, thermal decomposition a me nā ʻenehana ʻē aʻe, hiki ke hoʻohana ʻia ka solution ammonium molybdate ma ke ʻano he precursor no ka hoʻomākaukau ʻana i nā pauka ceramic molybdenum (e like me ke alakaʻi molybdate piezoelectric ceramics) me nā mea uila kūikawā, optical a catalytic properties, e like me nā mea hoʻopaʻa pale hana (nā lole pale pale)
ʻO ka hoʻomaka ʻana o nā pūhui molybdenum hou: Ma ke ʻano he kumu molybdenum, hoʻohana nui ʻia ka ammonium molybdate i nā keʻena hana a me nā noi ʻoihana e synthesize molybdenum disulfide (MoS ₂, lubricant paʻa, lithium negative electrode material), molybdenum based polyoxometalates (polyoxometalates me nā mea catalytic a me nā mea hana ʻē aʻe. (e like me nā mea photocatalytic, nā mea fluorescent).
6. ʻO ka ʻoihana uila: ʻo ka "behind the scenes hero" o ka hana pololei
Ma ka hana uila pololei, ua loaʻa pū ka ammonium molybdate i nā noi kikoʻī:
Mea hoʻonui i ka lapalapa ahi: Hoʻohana ʻia kekahi mau mea i loaʻa i ka ammonium molybdate e mālama i nā mea polymer (e like me nā ʻāpana insulation plastic no nā uea a me nā kaula, nā substrates circuit board), ma ka hoʻolaha ʻana i ka carbonization a me ka hoʻololi ʻana i ke ala decomposition thermal, e hoʻomaikaʻi ana i ka helu ahi retardant a me ka hana hoʻopau ʻana i ka uahi o ka mea.
Electroplating a me nā mea hoʻoheheʻe kemika: I nā kaʻina hana electroplating alloy a i ʻole nā kaʻina plating kemika, hiki ke hoʻohana ʻia ka ammonium molybdate ma ke ʻano he mea hoʻohui e hoʻomaikaʻi ai i ka glossiness, pale ʻana, a i ʻole ke kūpaʻa corrosion o ka uhi.
Mai ka puʻuwai hoʻomaʻemaʻe ʻaila e hoʻokele i nā moku nunui i nā huakaʻi lōʻihi a hiki i ka pale pale pale e pale ai i nā mea hana pololei; Mai kahi reagent koʻikoʻi e hōʻike ana i ke ʻano o nā mea phosphorus i loko o ka honua microscopic, i kahi ʻelele o nā ʻano mea e hānai ai i nā māla ākea; Mai nā iwi paʻakikī o nā ʻāpana wela kiʻekiʻe a i ke kumu hou o nā mea hana ʻokiʻoki - ka palapala noi oammonium molybdate- hoʻokūpaʻa loa i ke kūlana kumu o nā kemika kumu i ka moʻomeheu ʻenehana hou.
