异丙嗪与离子的反应及其用作VO_3^-检定的研究

Detection of VO_3^- by using promethazine

将异丙嗪用作新无机分析试剂,报导了异丙嗪与70种离子的反应情况,给出了异丙嗪与VO-3进行显色反应的最佳条件、灵敏度、选择性和界限比,建立了检定VO-3的新方法。

A method of detection of VO^-_3 was developed bosed on the reaction of VO^-_3 with promethazine. The optimal conditions, the sensitivity and selectivity for the detection was studied. The detection limit was 0.01 μg and dilution limit was 1: 5×10~6.
