- 中文摘要:
Cobalt, nickel and palladium have been extracted with thioxanthate into molten naphthalene (85-90℃). Various parameters involved in the extraction have been studied and composition of the extracted complex established in each case. Cobalt, nickel and palladium thioxanthates are extracted in the pH range, Co: 5.0-9.5, Ni:3.9-7.4 and Pd:2.0-9.5 and can be determined spectrophotometrically at 390,500 and 345nm respectively. The molar absorptivities are calculated to be Co:6.187×10…
Mol-1 cm-1, Ni:8.8×10…mol-2 cm-1 and Pd: 1.16×10… mol-1 cm-1 with sensitivities in terms of sandell’s defication are;0.0095… Co/cm2 at 390nm, 0.0060… Ni/cm2 at 500nm and 0.0091… Pd/cm2 at 345mn respectively. These conditions have been utilized for the determination of these metals in alloys ands and also for the simultaneous determination of cobalt and nickel in an alloy. - 英文摘要: --
