具体实施方式
下面结合实施例对本发明进行详细说明。
本发明是一种环境友好型降解抗生素盐酸环丙沙星的新型应用技术，其使用水热合成法制备出钨酸盐半导体材料CaWO4，并与超声技术相配合，用以催化超声降解盐酸环丙沙星模拟的制药废水。超声降解是20世纪90年代初新发展起来的一种高效降解有机污染物的处理方法，其原理是利用超声在溶液介质中产生的空化效应，使有机物降解并达到矿化。因此超声波的空化效应以及由此引发的物理和化学变化才是有机物超声降解的根本原因。
本发明把两者结合起来降解盐酸环丙沙星，通过实验证明该技术的可行，该技术在超声降解抗生素废水方面效果明显。
实施例1：由图2可知，在CaWO4存在和超声条件下，盐酸环丙沙星的降解率随着加入量从0.5增加到1逐渐增加，再随着加入量1到2增加而逐渐降低，说明CaWO4催化超声降解盐酸环丙沙星与催化剂比为1：1时最佳。
实施例2：改变超声功率来研究降解盐酸环丙沙星的效果，实验中，CaWO4的加入量为1.0 g/L，超声照射时间为120 min,染料溶液的pH为6，盐酸环丙沙星的浓度为10 mg/L，超声装置的输出功率设定在80-200 W范围内。由图3可知，当超声功率逐渐增加时，盐酸环丙沙星的降解率也明显增加。
实施例3：CaWO4对盐酸环丙沙星的降解率的实验是在加入量1 g/L进行的，超声照射时间为120min，盐酸环丙沙星的浓度为10mg/L，溶液的pH为6，超声装置的功率为200 W。取80 mL10mg/L的盐酸环丙沙星溶液，加入准确称取的一定量1 g/L的纳米CaWO4粉末，于暗处磁力搅拌30 min。取悬浮液在经超声照射2h后，取样离心分离后取上清液。盐酸环丙沙星的降解率为70.75%。
实施例4：由图5可知，表明了CaWO4具有良好的可重复利用性，可以重复多次使用。
