摘要

In this study, a set of branched polyethyleneimine (BPEI) modified magnetic biochar composites (BPEI500-MBC, BPEI1800-MBC and BPEI20000-MBC) were successfully prepared for capturing Cr(VI) from water solution. The results of the adsorption experiment showed that the adsorption capacity obeyed the sequence of BPEI500-MBC更多
