Application of coconut shell biochar-loaded iron and cobalt bimetallic materials for catalyzing peroxymonosulfate degradation of tetracycline hydrochloride
摘要
Abstract
[Objectives]The aim of this paper was to synthesize coconut shell biochar-loaded iron and cobalt bimetallic materials using recovered coconut shell charcoal from water dispensers,and further to apply them in the degradation of tetracycline by catalyzing peroxymonosulfate(PMS).[Methods]The microstructures of the prepared materials were characterized by scanning electron microscope,X-ray electron energy spectrum,infrared spectrum and X-ray powder diffraction.The performance of the material in the degradation of tetracycline hydrochloride under different conditions was compared to find the optimal conditions,and the degradation mechanism was inferred by quenching experiments and electron paramagnetic resonance(EPR)analyses.[Results]Characterizations results confirmed that the bimetallic loading of coconut shell biochar materials had been successfully synthesized.The materials showed the best degradation effect at an initial pH5,a PMS concentration of 0.75 mmol·L-1,and a catalyst incorporation of 0.20 g·L-1,in which the removal rate of tetracycline hydrochloride(TCH)was greater than 92.5%after 40 min.[Conclusions]In this work,coconut shell biochar-loaded iron and cobalt bimetallic materials were synthesized successfully,in which the excellent catalytic performance of degradation tetracycline hydrochloride by PMS was highly efficiently,and little affected by humic acid.The prepared material had a broad application prospect in the field of environmental remediation.关键词
