摘　　要：报道了分子筛负载杂多酸和二氧化钛催化剂MS/HPA/TiO2的制备及其对品红溶液降解的效果,系统研究了催化品红溶液降解的优化条件。实验表明,MS/HPA/TiO2具有良好的催化活性且容易回收。当MS∶HPA∶TiO2=1∶10∶1,品红的浓度为0.005%(10mL),催化剂的用量为10mg,反应时间为10m in,品红的降解率达到96.87%。The catalyst of MS/HPA/TiO2 by heteropolyacid and titanic oxide supported on molecular sieve was prepared and using it as catalyst on degradation of fuschin red was also studied, then the optimum condition of degradation of fuschin red were obtained. It showes that MS/HPA/TiO2 is an excellent catalyst. With MS/HPA/TiO2 = 1： 10： 1,and 10mL fuschin red （0.005%） , 10mg catalyst reacted for 10 min, the degradation of fuschin red can reach 96.87%.
