摘　　要：采用聚多巴胺(PDA)对钴-钴普鲁士蓝类似物(PBA_(Co-Co))进行改性,通过简单的原位聚合法成功制备了聚多巴胺-普鲁士蓝类似物复合材料(PDA@PBA_(Co-Co)),并用来活化过一硫酸盐(PMS)去除水中的盐酸四环素(TCH)。催化降解实验结果表明,在20℃、120min内,300mg/L的氧化剂和100mg/L的催化剂对15mg/LTCH的去除效果能达到97.1%。经过4次循环实验,盐酸四环素的去除率仍能达到91.6%,表现出了较为优异的稳定性和重复利用性。PDA改性促进了Co^(3+)/Co^(2+)的氧化还原循环,增强了催化活性。PDA@PBA_(Co-Co)复合材料制备简单,具有高催化活性,可重复使用,是一种有效的废水修复催化剂。Polydopamine(PDA)was used to modify cobalt-cobalt Prussian blue analogue(PBA_(Co-Co)).Polydopamine-Prussian blue analogue composite(PDA@PBA_(Co-Co))was successfully prepared by a simple in-situ polymerization method,for peroxymonosulfate(PMS)to remove tetracycline hydrochloride(TCH)in water.The results of catalytic degradation experiments showed that the removal efficiency of 15 mg/L TCH by 300 mg/L Oxone and 100 mg/L catalyst could reach 97.1%within 120 min at 20℃.After four cycles of experiments,the removal efficiency of TCH could remain 91.6%,showing excellent stability and reusability.The redox cycle of Co^(3+)/Co^(2+)was promoted and the catalytic activity was enhanced by PDA modification.The PDA@PBA_(Co-Co)composite material is easy to prepare,with high catalytic activity and reusability,which can be an effective catalyst for wastewater remediation.
