采用分光光度法研究了磺化酞菁镓在不同ｐＨ溶液中的二聚现象及在碱性溶液中的分解动力学，测定了二聚常数ＫＤ和分解速率常数ｋｏｂｓ，结果表明：磺化酞菁镓的分解速度方程可表示为：－ｄｃＤｄｔ＝１２．２７ｃＯＨ－ｃＤ，式中ｃＤ、ｃＯＨ－分别为溶液中磺化酞菁镓二聚体和碱的浓度。
Spectrophotometry was used to study the dimerization of sulfonated phthalocyanine gallium in different pH solutions and the kinetics of its decomposition in alkaline solution. The dimeric constant KD and decomposition rate constant kobs were determined. The results showed that sulfonated phthalocyanine The gallium decomposition rate equation can be expressed as: -dcDdt = 12.27cOH-cD, where cD and cOH- are the concentration of sulfonated phthalocyanine gallium dimer and base, respectively, in the solution.
