Sodium iodide bụ ihe siri ike ọcha nke a na-enweta site na mmeghachi omume dị n'etiti sodium carbonate na hydroiodic acid na mmịpụta mmiri nke mmiri ahụ. E nwere ihe mejupụtara anhydrous, dihydrate na pentahydrate. Ọ bụ ihe eji emepụta iodine, maka iji ya na ọgwụ na foto. Ngwọta acidic nke sodium iodide, n'ihi mmepụta nke hydroiodic acid, na-egosipụta ikike mbelata.
Njirimara Ngwaahịa
Sodium iodide bụ ntụ ntụ kristal ọcha nke na-enweghị agba. Ọ naghị esi isi ma nwee ụtọ nnu dị ilu. Ọ na-amịkọrọ mmiri site na ikuku; ọ na-agbanwe aja aja nwayọ nwayọ mgbe ọ kpugheere ikuku n'ihi na iodine gbanwere; njupụta ya bụ 3.67g/cm3; ọ na-agbaze na 660°C; ọ na-agbaze na 1,304°C; nrụgide uzuoku bụ torr 1 na 767°C na torr 5 na 857°C; ọ na-agbaze nke ukwuu na mmiri, 178.7 g/100 mL na 20°C na 294 g/100 mL na 70°C; ọ na-agbaze na ethanol na acetone.
Ngwa
A na-eji sodium iodide eme ihe nke ukwuu maka mgbanwe halide (mmeghachi omume Finkelstein), dịka ọmụmaatụ na mgbanwe nke alkyl chloride, allyl chloride na arylmethyl chloride ka ọ bụrụ iodides ha, nke bụ ihe ndị na-ebute ụzọ maka ngwaahịa ọgwụ na kemịkalụ dị mma. A na-eji ha eme ka arụmọrụ nke mmepụta Wittig adducts site na chlorides na bromides na-adịghị arụ ọrụ. A na-eji nkwadebe kwesịrị ekwesị eme ihe dị ka ihe mgbakwunye nri. A na-eji sodium iodide eme ihe dị ka ihe na-ebute ụzọ na njikwa na ab initio emulsion polymerization. A na-ahụ na sodium iodide na-eji ya na mkpebi nke oxygen agbazere na usoro Winkler agbanwere, njikọ nke agba fluorescent coppersensor-1 (CS1) maka onyonyo ọdọ mmiri ọla kọpa labile na ihe atụ bayoloji, na nkewa nke esters, lactones, carbamates na ethers na njikọta na chlorotrimethylsilane.
Enwere ike iji ya maka cystography, retrograde urography, cholangiography site na T-tube na fistula angiography nke akụkụ ndị ọzọ.
Urography: 6.25% 100ml. Cystography: 6.25% 150ml. Retrograde pyelography: 12.5% 5 ~ 7ml. T-tube cholangiography: 12.5% 10 ~ 30ml. Fistula angiography: chọpụta ebe a na-agba ọgwụ na dose dịka ọnọdụ ọrịa ahụ si dị.
E jiri sodium iodide mee ihe dị ka ihe dị mkpa n'ịkwadebe ihe ngwọta ntụpọ nke Mayer's hematoxylin.
Enwere ike iji ya mee ihe n'usoro ndị a:
Ihe na-eme tupu e mepụta polymerization nke butyl acrylate.
Onye na-eme ka ihe dị iche iche dị na DNA.
Ihe na-egbochi ihe nchekwa na mwepụ nke otu N-tert-butyloxycarbonyl na amino acid.
Ihe na-eme ka fluorescence gwụchaa mmiri.
