摘　　要：以硝酸铋,磷酸三钠采用水热法,在pH为1的条件下制备了BiPO_4催化剂,进行SEM、XRD、XPS和UV-Vis等表征。在300 W氙灯照射下,测试样品对四环素的光降解能力。结果表明,实验制备的BiPO_4为八面体形貌,其晶型单斜相型,反应80 min后,对浓度40 mg/L四环素的降解率可达54%。The BiPO 4 was prepared by hydrothermal method with bismuth nitrate and trisodiun phosphate under the pH of 1.The samples were characterized by SEM,XRD,XPS and UV-Vis,whose photocatalysis performance under a 300 W xenon lamp has been studied when tetracycline as target pollutant.The result shows that BiPO 4 is octahedral.Moreover,the crystalline form is monoclinic.The degradation rate of 40 mg/L concentration of tetracycline reached 54%after 80 min.
