摘要
本文建立了锌净化液中微量锑的反向流动注射分光光度测定法。锑-水杨基荧光酮-乳化剂OP是个较灵敏的显色体系,巯基乙酸能使该体系褪色完全,据此可将巯基乙酸注入到载流中测定注入前后吸光度的差值,作为定量的依据。测定波长为506nm,测定范围为0.0～1.0μg/mL,采样体积为30μL,采样频率为30次/h。
A reverse flow injection analysis ( r- FIA )- spec-trophotometric method for the determination of Sb in purified solution of zinc hydrometallurgy has been established. The system of Sb-SAF-OP is sensitive, the colour of the complex can be faded with thioglycollic acid and a method for the determination of antimony has been developed. The maxium absorption is at 506nm and Beer's law is obeyed in the range of 0～l.0μg/mL Sb. The sampling volume is 30μL and the sampling frequency is 30 sampl-es/h.
