聚多巴胺改性钴-钴普鲁士蓝类似物活化过一硫酸盐降解盐酸四环素
Polydopamine modified cobalt-cobalt Prussian blue analogue for peroxymonosulfate activation to degrade tetracycline hydrochloride
摘要
Abstract
Polydopamine(PDA)was used to modify cobalt-cobalt Prussian blue analogue(PBACo-Co).Polydopamine-Prussian blue analogue composite(PDA@PBACo-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 Co3+/Co2+was promoted and the catalytic activity was enhanced by PDA modification.The PDA@PBACo-Co composite material is easy to prepare,with high catalytic activity and reusability,which can be an effective catalyst for wastewater remediation.关键词
