2. ọ na-atụgharị edo edo n'ụzọ dị mfe na ngwọta mmiri acidic.Potassium iodide bụ ihe na-agba ume nke ayodiin.Mgbe agbazere, ọ na-etolite potassium triiodide na ayodiin, na atọ ndị ahụ na-nha nhata.
3. potassium iodide bụ ihe oriri iodine kwadoro, nke enwere ike iji na nri ụmụ ọhụrụ dịka iwu ndị China si dị.Usoro onunu ogwu bụ 0.3-0.6mg / kg.Enwere ike iji ya mee nnu nnu.Usoro onunu ogwu bụ 30-70ml / kg.Dị ka akụkụ nke thyroxine, ayodiin na-ekere òkè na metabolism nke ihe niile dị na anụ ụlọ na anụ ọkụkọ ma na-edobe nguzozi okpomọkụ dị n'ime.Ọ bụ hormone dị mkpa maka uto na mmepụta anụ ụlọ na anụ ọkụkọ.Ọ nwere ike melite arụmọrụ nke anụ ụlọ na anụ ọkụkọ ma kwalite ahụike nke ahụ.Ọ bụrụ na ahụ anụ ụlọ na anụ ọkụkọ bụ erughi na ayodiin, ọ ga-eduga na metabolic ọrịa, ahụ ọrịa, goiter, emetụta akwara ọrụ, akpụkpọ agba na ndepụta mgbaze na absorption, na-emecha na-eduga ngwa ngwa ibu na mmepe.
Ọ na-agbaze ngwa ngwa na mmiri ma na-amịkọrọ okpomọkụ mgbe agbazere.The solubility na 100g mmiri bụ 127.5g (0 ℃), 144g (20 ℃), 208g (100 ℃).N'ihe banyere ikuku mmiri na carbon dioxide, ọ ga-erepịa ma gbanwee edo edo.Soluble na methanol, ethanol na glycerol.Iodine na-agbaze ngwa ngwa na ngwọta mmiri nke potassium iodide.Ọ na-ebelata ma enwere ike ime ya site na oxidizing agents dị ka hypochlorite, nitrite na ion ferric iji hapụ iodine n'efu.Ọ na-emebi emebi mgbe ekpughere ya n'ìhè, ya mere a ga-echekwa ya na ebe mkpuchi, ọchịchịrị na ebe dị jụụ.Na mgbakwunye na eji ya maka ọgwụ na foto, a na-ejikwa ya dị ka reagent nyocha.
Njirimara na nkwụsi ike:
1. A na-ejikarị potassium iodide eme ihe dị ka ihe mgbochi corrosion maka pickling ígwè ma ọ bụ synergist nke ndị ọzọ corrosion inhibitors.Potassium iodide bụ akụrụngwa maka ịkwadebe iodide na agba.A na-eji ya dị ka emulsifier foto, ihe mgbakwunye nri, expectorant na diuretic na ọgwụ, ọgwụ maka mgbochi na ọgwụgwọ nke goiter na hyperthyroidism tupu arụ ọrụ, yana reagent nyocha.Ejiri ya na ụlọ ọrụ foto dị ka emulsifier foto, nke a na-ejikwa dị ka ọgwụ na mgbakwunye nri.
2. eji dị ka nri mgbakwunye.Iodine, dị ka akụkụ nke thyroxine, na-ekere òkè na metabolism nke ihe niile dị na anụ ụlọ na anụ ọkụkọ ma na-eme ka okpomọkụ dị n'ime ahụ.Iodine bụ hormone dị mkpa maka uto, mmepụta na lactation nke anụ ụlọ na anụ ọkụkọ.Ọ nwere ike melite arụmọrụ nke anụ ụlọ na anụ ọkụkọ ma kwalite ahụike nke ahụ.Ọ bụrụ na ahụ anụ ụlọ na anụ ọkụkọ bụ erughi na ayodiin, ọ ga-eduga na metabolic ọrịa, ahụ ọrịa, goiter, emetụta akwara ọrụ, mgbaze na absorption nke uwe na agba na ndepụta, na-emecha na-eduga ngwa ngwa ibu na mmepe.
3. ụlọ ọrụ nri na-eji ya dị ka ihe oriri na-edozi ahụ (iodine fortifier).Enwere ike iji ya dị ka mgbakwunye nri.
