为研究磷灰石复合光催化剂光催化降解性能，选择球形羟基磷灰石(HAP)为基体材料与二氧化钛复合，制备磷灰石复合光催化剂处理异丁基黄药模拟废水，考察了pH值、光照时间、光照条件、初始质量浓度等条件对异丁基黄药催化降解效果。结果表明，初始质量浓度为50 mg/L，pH值为3.6且在紫外光下照射6 min，异丁基黄药降解率可达99.993%，残余质量浓度低于0.005 mg/L，达到国家地表水环境质量标准。

In order to study the apatite composite photocatalyst which has a certain structure for degradation effect of the simulated wastewater of isobutyl xanthatethe, we select carboxymethyl cellulose(CMC) as the template and use ultrasonic oscillation to synthesis HAP. Then use HAP as matrix material to composite with tetrabutyl titanate to preparate apatite composite photocatalyst TiO2/HAP, respectively inspected the pH valu e,illumination, reaction time, initial concentration of xanthate on catalytic degradation of isobutyl xanthate. The results showed that, when the isobutyl xanthate initial concentration is 50 mg/L, pH=3.6 and irradiated under UV light for 6 min, the isobutyl xanthate degradation rate is up to 99.993%when the residual concentration is below 0.005 mg/L, and reached the surface water environmental quality standards of national.
