The experimental results indicates that the optimum pH range was 1.60~2.20, and the optimum H2O2 concentration was 10.0 mmol/L. The degradation ratio increased with the increasing concentration of ammonium ferric oxalate in the range from 0.1 to 1.0 mmol/L, but no significant increase in degradation ratio was observed when the concentration was above 1.0 mmol/L. When the concentration of fuchsin basic increased, the degradation ratio dropped, while the concentration of degraded fuchsin basic rised. When the concentration of fuchsin basic was low, the degradation followed first-order kinetics, but when it was high, the degradation could be fitted by zero-order kinetics. The absorbtion of fuchsin basic at 543 nm disappeared quickly, while the absorbtion of intermediates formed during the course of fuchsin basic dagradation at 298 nm vanished slowly.

试验结果表明：碱性品红降解的最佳初始pH为1.60~2.20，最佳初始H2O2浓度为10.0mmol/L；草酸高铁铵的浓度在0.1~1.0mmol/L时，碱性品红的降解率随浓度的增大而增大；高于1.0mmol/L时，则降解率相差不大；碱性品红的初始浓度增大，降解率减小，而实际降解的浓度则增加；碱性品红的浓度在低和高时，降解动力学过程不一致；随降解的进行，碱性品红在可见光区的吸收峰迅速消失，而降解过程中形成的中间产物吸收峰却消失很慢。
