摘要
生物质炭材料易制备且吸附性能优越,在水体中重金属污染处理方面极具应用前景。本文以不同金属盐(氯化盐、硝酸盐和硫酸盐)作为改性剂,通过一步水热法成功合成了桉树皮水热炭,研究了水热炭对水溶液中的六价铬(Cr(Ⅵ))的吸附性能。确定了氯化盐为最佳改性剂,并通过研究不同金属氯化盐溶液浓度和水热温度对水热炭吸附性能的影响,优化了水热炭的制备条件。
Biomass carbon material is easily prepared and have superior adsorption performance,which has great application prospect in the treatment of heavy metal pollution in water.In this paper,different metal salt(chloride,nitrate and sulfate)were used as modifying agent.The adsorption performance of modified hydrochars on hexavalent chromium(Cr(Ⅵ))in aqueous solution was investigated.The chloride salt was determined as the best modifier,and the preparation conditions of the hydrochar were optimized by studying the effects of different metal chloride salt concentrations and hydrothermal temperatures on the adsorption performance of the hydrochars.
