摘　　要：以化学沉淀法成功制备了类花状羟基磷灰石(HAP),考察了HAP用量、H_(2)O_(2)用量及溶液初始浓度等因素对HAP/H_(2)O_(2)体系降解结晶紫溶液的影响.结果表明,在100 mL 30 mg·L^(-1)结晶紫溶液加入0.01 g HAP和0.1 mL H_(2)O_(2),反应38 min时,脱色率可达97.2%,动力学研究表明该降解过程符合准二级动力学方程.Flower-like hydroxyapatite(HAP)was synthesized by chemical precipitation method.The effects of HAP dosage,H_(2)O_(2)dosage and initial solution concentration on the degradation of crystal violet(CV)were investigated using flower-like hydroxyapatite as catalyst.The results showed that when 0.01 g HAP and 0.1 mL H_(2)O_(2)are added to 100 mL of 30 mg·L^(-1)crystal violet solution,after 38 min of reaction,the decolorization rate of crystal violet is attained to 97.2%.Kinetic studies indicated that the degradation process is approximately pseudo-second order kinetic equation.
