摘要非活体干燥水葫芦根的生物量，凤眼莲，表现出高吸附铜从水溶液中。最大吸附量为20.90 mg Cu/g，由Langmuir等温线确定。研究了影响吸附的几个因素。它们包括pH值、初始浓度、螯合剂和其他金属的存在的影响。还讨论了在填充床系统中使用该材料从电镀废物中去除铜的可行性。
Abstract Biomass of non‐living dried water hyacinth roots, Eichhornia crassipes, showed high sorption for copper from aqueous solutions. Maximum sorption was 20.90 mg Cu/g as determined from Langmuir isotherm. Several factors affecting sorption were investigated. They include effect of pH, initial concentrations, presence of chelators and other metals. The feasibility of removing copper from electroplating waste using this material in a packed‐bed system was also discussed.
