摘　　要：采用反相离子对高效液相色谱法研究了活性艳橙K-G水解反应动力学.当染料溶液中碱基过量时,可视为一级反应.在pH值为13时,ln(A0/A)与反应时间呈线性关系,反应速率常数是pH 8.5时的2.7倍;95℃时,ln(A0/A)与反应时间呈线性关系,反应速率常数是70℃时的3.7倍.Hydrolysis kinetics of reactive brilliant orange K-G was studied with reverse phase HPLC,The hydrolysis was regarded as first order reaction when OH-was excessive in dye solution.at pH value 13,ln（A0/A） was linear with reaction time,reaction rate constant was 2.7 times as that at pH value 8.5;at 95 ℃,ln（A0/A） was linear with reaction time,reaction rate constant was 3.7 times as that at 70 ℃.
