胶束增敏导数分光光度法测定微量铜

Determination of Micro Copper in Micelle with 1-(2-Pyridylazo)-2-Naphthol by Derhative Spectrophotometry

本文研究了在非离子型胶束TritonX－100体系中，以1－（2-吡啶偶氮）－2一萘酚（PAN）为显色剂，用二阶导数分光光度法消除镉的干扰，与乙醇介质比较，测定灵敏度提高，测定镉样中微量钢，结果较为满意。

A derhathe spectrophotometric method, based on the use of second derivative absorption spectra,has been developed for the determination of microgra-m amount of copper with 1-(2-PyTidylazo)-2-naphthol in Triton 'X-100 micelle medium- The peak to base line measurement technique has been used with good results, Using the proposed method copper (2- 20μg/25mL ) has been determined with good precision and accuracy.
