Codsiga: Daawaynta Xayawaanka ama Farmashiyaha
Sodium iodide waa cad adag oo laga helo falcelinta u dhaxaysa sodium carbonate oo leh hydroiodic acid iyo uumi-baxa dheeraadka ah ee xalka. Waxaa jira isku-darka aan biyo lahayn, dihydrate iyo pentahydrate. Waa walaxda ceeriin ah ee loo isticmaalo soo saarista iodine, si loogu isticmaalo daawada iyo sawir-qaadista. Xalka aashitada leh ee sodium iodide, oo ay ugu wacan tahay soo saarista hydroiodic acid, wuxuu muujiyaa awood yarayn.
Sifooyinka Badeecada
Sodium iodide waa budo crystalline ah oo aan midab lahayn ama budo crystalline cad. Waa mid aan ur lahayn oo dhadhan milix leh qadhaadh leh. Waxay qoyaanka ka nuugtaa hawada; si tartiib tartiib ah ayuu bunni isu beddelaa marka uu hawada soo gaaro sababtoo ah iodine-ku wuu isbeddelay; cufnaanta 3.67g/cm3; waxay dhalaalaysaa 660°C; wuu uumi baxaa 1,304°C; cadaadiska uumiga 1 torr 767°C iyo 5 torr 857°C; aad ayuu ugu milmaa biyaha, 178.7 g/100 mL heerkul ah 20°C iyo 294 g/100 mL heerkul ah 70°C; wuxuu ku milmaa ethanol iyo acetone.
Codsiga
Sodium iodide waxaa si weyn loogu isticmaalaa is-weydaarsiga halide (falcelinta Finkelstein), tusaale ahaan beddelka alkyl chloride, allyl chloride iyo arylmethyl chloride una beddelaan iodides-kooda, kuwaas oo ah hordhac u ah alaabada dawooyinka iyo kiimikada wanaagsan. Waxaa loo isticmaalaa in lagu xoojiyo waxtarka sameynta adducts-ka Wittig ee ka yimaada chlorides iyo bromides-ka aan firfircooneyn. Diyaargarowga ku habboon wuxuu u isticmaalaa sidii kabitaan nafaqo. Sodium iodide waxaa loo isticmaalaa sidii horudhaca wakiilka xakamaynta ee polymerization-ka emulsion-ka ab initio. Sodium iodide wuxuu u isticmaalaa go'aaminta oksijiinta milmi karta ee habka Winkler ee wax laga beddelay, isku-darka coppersensor-1 fluorescent dheehka-1 (CS1) si loo sawiro barkadaha naxaasta ee labile ee muunadaha bayoolojiga, iyo kala-goynta esters-ka, lactones-ka, carbamates-ka iyo ethers oo lagu daray chlorotrimethylsilane.
Waxaa loo isticmaali karaa cystography, retrograde urography, cholangiography iyada oo loo marayo T-tube iyo fistula angiography ee qaybaha kale.
Urography: 6.25% 100ml. Cystography: 6.25% 150ml. Dib-u-soo-celinta pyelography: 12.5% 5 ~ 7ml. Kolangiography-ga T-tube: 12.5% 10 ~ 30ml. Fistula angiography: go'aami goobta duritaanka iyo qiyaasta iyadoo loo eegayo xaaladda cudurka.
Sodium iodide waxaa loo isticmaalay qayb ka mid ah diyaarinta xalka wasakhda hematoxylin ee Mayer's.
Waxaa loo isticmaali karaa hababka soo socda:
Horudhac ku saabsan polymerization-ka butyl acrylate.
Wakiilka Chaotropic ee soo saarista DNA-da.
Wakiilka ka-hortagga ee ka saarista kooxda N-tert-butyloxycarbonyl ee ku jirta amino acids.
Damiye dab-damis ah oo iftiin-dhalaal ah oo biyo ku milma.
Baakaynta iyo Kaydinta
Baakad: Foorno kartoon ah oo lagu dahaadhay bac balaastik ah, 25KG/durbaan.
Kaydinta: La shaabadeeyey oo lagu kaydiyey mugdiga.
