摘　　要：在pH2.5的硫酸介质中,锑(Ⅲ)与溴邻苯三酚红生成的络合物产生一个灵敏的导数极谱波,其导数波峰值电位为-0.56V(vs.SCE),线性范围0.01～0.5μg/mL,许多离子不干扰测定,不需要分离与富集,直接测定锌浸出液中不同含量的锑。The electroactive complex, Sb(Ⅲ)bromopyrogallol red was formed in the sulfuric acid solution(pH 2.5),and showed a sensitive derivative polarographic wave at -0.56V(vs.SCE).The linear range of Sb(Ⅲ)was 0.01～0.2 μg/mL, The method was successfully applid to the determination of Sb in different zinc lixiviating solutions.
