Āhua: paura ma, tata ma rānei, he karaihe kore tae rānei
He tioata pūtoru mā, he paura rānei te pāhare pākawa waro. He paku waikura i te hau makuku, ka roa te wā ka puta te iodine kore utu, ka huri hei kōwhai, ā, ka taea te hanga i tētahi iti o te iodate. Ka taea e te mārama me te makuku te whakatere i te pirau. I whakarewaina te 1 karamu ki te 0.7 ml o te wai, 0.5 ml o te wai kohua, 22 ml o te etanoru, 8 ml o te etanoru kohua, 51 ml o te etanoru tino, 8 ml o te methanol, 7.5 ml o te acetone, 2 ml o te glycerol, me te 2.5 ml o te ethylene glycol. He kūpapa, he paku kawakore rānei tōna wairewa, ā, ka taea te whakarewa i te iodine. Ka waikura anō hoki te wairewa ka huri hei tae kōwhai, ka taea te ārai mā te tāpiri i tētahi iti o te kawakore. Ko te mātotoru whanaunga ko te 3.12. Ko te pāmahana he 680 °C. Ko te ira kohua he 1330 °C. Ko te horopeta whakamate tata (kiore, uaua) he 285 mg/kg. He whānui te whakamahinga i roto i te tātari rōrahi o ngā tikanga iodometric hei whakarite i ngā wairewa titration. Ko ngā momo rongoā pēnei i a Beredes, Modified White, MS, me RM ka whakaritea i roto i ngā momo haplotype. Whakamātautau paru, me ētahi atu. Whakaahua. Rongoā.

Pāhare pākawa iodideHe puna iodine, he matūkai, he tāpiringa kai hoki. Kei te noho hei tioata, hei paura rānei, ā, ko te wairewatanga he 1 karamu i roto i te 0.7 ml o te wai i te 25°C. Kei roto i te tote tepu hei ārai i te mate puku. Ko te Potassium Iodide te mea matua e whakamahia ana hei rongoā i te paihana irahiko nā te poke o te taiao e te iodine-131. Kei te hangaia hoki he emulsion whakaahua; i roto i ngā whāngai kararehe me ngā heihei tae atu ki te 10-30 wāhanga ia miriona; i roto i te tote tepu hei puna iodine me ētahi wai inu; i roto hoki i te matū kararehe. I roto i te rongoā, ka whakamahia te potassium iodide hei whakahaere i te repe tairoi.
I whakamahia tuatahitia te pāhare pākawa hei halide matua i roto i te tukanga calotype a Talbot, kātahi i roto i te tukanga albumen i runga i te karāhe, ā, i muri mai ko te tukanga collodion mākū. I whakamahia anō hoki hei halide tuarua i roto i ngā emulsions gelatin hiriwa bromide, ngā whāngai kararehe, ngā whakakorikori, ngā matū whakaahua, me te horoi. Ka puta te pāhare pākawa mā te tauhohenga o te pāhare pākawa me te iodine. Ka purea te hua mā te tioata mai i te wai. Ko te pāhare pākawa he matū ionic ka taea e ngā iona iodine me ngā iona hiriwa te hanga i te iodide hiriwa kōwhai (ina whakaatuhia ki te mārama, ka taea te pirau, ka taea te whakamahi hei hanga kiriata whakaahua tere-tere), ka taea te whakamahi i te nitaita hiriwa hei manatoko i te aroaro o ngā iona iodine.
1.Takai: Ko te tikanga 25kgs ia pahu kātene.
2.MOQ: 1kg
3. Wā tuku: Ko te tikanga 3-7 ngā rā i muri i te utu.
