摘要
本文合成了复合生物炭的FeOCl复合材料(FeOCl/BC),并用于活化过硫酸盐降解四环素,系统评价了四环素浓度、催化剂用量、PDS剂量等参数对催化剂活性的影响。结果显示,FeOCl/BC显著提升了PDS分解生成过硫酸根自由基(SO_(4)^(−)·)的效率。降解四环素的较佳条件为:四环素初始浓度为10mg·L^(-1),FeOCl/BC的使用量为0.3g·L^(-1),PDS的浓度为0.3g·L-1。体系中NO_(3)^(-)、SO_(4)^(2-)、H_(2)PO_(4)^(-)的存在对四环素降解效率的影响不大,Cl^(-)对促进四环素的降解有利,HCO_(3)^(-)的存在对四环素的降解有一定的抑制效应。
A composite catalyst FeOCl/BC was synthesized and used to activate persulfate(PDS)to degrade tetracycline.The effects of tetracycline concentration,catalyst and PDS dosage on catalytic activity of catalyst were systematically evaluated.The results showed that FeOCl/BC significantly improved the decomposition efficiency of PDS to generate persulfate radical(SO_(4)^(-)·).The optimal conditions for degradation of tetracycline were as followed:initial concentration of tetracycline was 10mg/L,dosage of FeOCl/BC was 0.3g/L and concentration of PDS was 0.3g/L.The existence of NO_(3)^(-),SO_(4)^(2-)and H_(2)PO_(4)^(-)had little effect on the degradation efficiency of tetracycline,while Cl-was beneficial to promote the degradation of tetracycline,the HCO_(3)^(-)had certain inhibitory effect on the degradation of tetracycline.
