SIRKONIY(IV) IONNI 1-(2-GIDROKSI-1-NAFTOYAZO)-2-NAFTOL-4-SULFOKISLOTA ERITMASI BILAN EKSTRAKTSION SPEKTROFOTOMETRIK ANIQLASH
##submission.downloads##
Sirkoniy (IV) ionini 1-(2-gidroksi-1-naftoyazo)-2-naftol-4-sulfokislotaning xloroformdagi eritmasi yordamida ekstraksion -
spektrofotometrik usuli ishlab chiqildi. Sirkoniy (IV) ionini ajratishga ta’sir qiluvchi omillar: erituvchining tabiati, ion kuchining
taʻsiri, suvli va organik qavat hajmining nisbati 4 : 1, taqsimlanish koeffitsiyenti 0.92 ekanligi va Y (8.9 mkg), Nd (9.3 mkg),
Mo (9.6 mkg), Tc (9.8 mkg), Sr (8.7 mkg), Ru (10.1 mkg) va Rh (10.3 mkg) ionlarining halaqit bermasligi aniqlandi.
