摘　　要：超声作用下,五水硫酸铜经抗坏血酸还原后获得产物铜,对产物进行扫描电镜和X射线衍射表征以及催化性能测试。结果表明:产物铜形貌为棍棒状和不规则粒状,铜催化剂对染料次甲基蓝、结晶紫、茜素红和罗丹明B有着良好的催化氧化性能,10 mg催化剂铜对6 mg/L次甲基蓝的催化效率达到了98.1%,且催化剂催化效率随催化剂用量的增加和染料溶液浓度的降低而增加。Under the action of ultrasound,product was obtained through copper sulphate pentahydrate reduced by ascorbic acid,the product was characterized by scanning electron microscopy and X-ray diffraction and the catalytic performance test. The result showed that the product was copper with stick and irregular shape,the catalyst copper had good catalytic oxidation performance on methylene blue,crystal violet,alizarin red and rhodamine B,the catalytic efficiency of 10 mg copper catalyst to 6 mg/L methylene blue had reached 98. 1%,and the catalytic efficiency of the catalyst increased with the amount of catalyst and the concentration of the dye solution.
