摘要
研究了铬天青Ｓ在不同ｐＨ缓冲溶液中的吸收光谱及一阶导数光谱，并据此拟定出一个测定各级离解常数的方法，推导出计算公式。测定方法简单，结果与文献值比较令人满意。
A new method for the determination of dissociation consents of chrome azurol S is proposed based on its first derivative spectra in buffer solution of different pH. The calculation formula are developed. The method is simple and the determination results are satisfactory.
