ʻAno: pauka keʻokeʻo a kokoke paha i ke keʻokeʻo a i ʻole ke aniani kala ʻole
He kristal cubic keʻokeʻo a pauka paha ka Potassium iodide. He hygroscopic iki ia i ka ea pulu, hoʻokahe i ka iodine manuahi no ka manawa lōʻihi a lilo i melemele, a hiki ke hana i kahi nui o ka iodate. Hiki i ka mālamalama a me ka makū ke hoʻolalelale i ka palaho. Ua hoʻoheheʻe ʻia ka 1 g i loko o 0.7 ml o ka wai, 0.5 ml o ka wai e paila ana, 22 ml o ka ethanol, 8 ml o ka ethanol e paila ana, 51 ml o ka ethanol absolute, 8 ml o ka methanol, 7.5 ml o ka acetone, 2 ml o ka glycerol, a ma kahi o 2.5 ml o ka ethylene glycol. He kūlike ʻole a alkaline iki paha kona hopena wai a hiki ke hoʻoheheʻe i ka iodine. E oxidize pū ka hopena wai a loli i kahi kala melemele, hiki ke pale ʻia ma ka hoʻohui ʻana i kahi liʻiliʻi o ka alkali. ʻO ka density pili he 3.12. ʻO ka mahana o 680 ° C. ʻO ke kiko paila he 1330 ° C. ʻO ka nui make (ʻiole, vein) he 285 mg/kg. Hoʻohana nui ʻia ia i ka loiloi volumetric o nā ʻano iodometric e hoʻomākaukau i nā hopena titration. Hoʻomākaukau ʻia nā ʻano hana like ʻole e like me Beredes, Modified White, MS, a me RM ma nā haplotypes. Hoʻokolokolo ʻana i ka fecal, a pēlā aku. Kiʻi. Lāʻau lapaʻau.

Potasiuma Iodidehe kumu ia o ka iodine a he meaʻai a he mea hoʻohui meaʻai. Loaʻa ia ma ke ʻano he kristal a pauka paha a he solubility o 1 g i loko o 0.7 ml o ka wai ma 25°c. Hoʻokomo ʻia ia i loko o ka paʻakai papaʻaina no ka pale ʻana i ka goiter. Hoʻohana nui ʻia ka Potassium Iodide i ka mālama ʻana i ka lāʻau make radiation ma muli o ka haumia o ke kaiapuni e ka iodine-131. Hana pū ia i nā emulsions kiʻi; i nā meaʻai holoholona a me nā manu a hiki i ka nui o 10-30 mau ʻāpana i ka miliona; i ka paʻakai papaʻaina ma ke ʻano he kumu o ka iodine a i loko o kekahi wai inu; pū kekahi i ka kemika holoholona. I ka lāʻau lapaʻau, hoʻohana ʻia ka potassium iodide e hoʻoponopono i ka thyroid gland.
Ua hoʻohana mua ʻia ka Potassium iodide ma ke ʻano he halide mua ma ke kaʻina hana calotype a Talbot, a laila ma ke kaʻina hana albumen ma ke aniani a ukali ʻia e ke kaʻina hana collodion pulu. Ua hoʻohana ʻia hoʻi ia ma ke ʻano he halide lua i nā emulsions gelatin bromide kālā, nā meaʻai holoholona, nā mea hoʻouluulu, nā kemika kiʻi, a no ka hoʻomaʻemaʻe. Hana ʻia ka Potassium iodide ma o ka hopena o ka potassium hydroxide me ka iodine. Hoʻomaʻemaʻe ʻia ka huahana ma o ka crystallization mai ka wai. ʻO ka Potassium iodide kahi hui ionic kahi e hiki ai i nā ion iodine a me nā ion kālā ke hana i ka melemele precipitate iodide kālā (ke hōʻike ʻia i ka mālamalama, hiki ke decompose, hiki ke hoʻohana ʻia e hana i kahi kiʻiʻoniʻoni kiʻi wikiwiki), hiki ke hoʻohana ʻia ka nitrate kālā e hōʻoia i ke alo o nā ion iodine.
1.Packing: ʻO ka maʻamau he 25kgs no ka pahu pepa.
2.MOQ: 1kg
3. Ka manawa hoʻouna: ʻO ka maʻamau he 3-7 mau lā ma hope o ka uku.
