All rights reserved.In order to remove mercury ions, Hg(II)-ion-imprinted polymers (Hg-IIPs) with silica core were synthesized by radical polymerization using complexes of Hg(II) ions with 3-mercaptopropyltrimethoxysilane ligands as a template, vinyl-trimethoxysilane as a monomer, and ethylene glycol dimethacrylate as a crosslinker, in the molar ratio 1: 6: 6. Silica, thiol, vinyl, carbonyl, and Hg(II) in the synthesis process were detected through FTIR, SEM-EDS, TGA, and BET analyses. Using Hg-IIPs as the sorbent, mercury ion removal was near optimal from a batch at pH 4 with an interaction time of 90 min, and gave 62.27 mg.g-1 adsorption capacity. The capture by Hg-IIPs of Hg(II) ions in the presence of Pb(II), Cd(II), and Cu(II) ions in quaternary solutions had the selectivity coefficients 46.92 for Hg/Cu, 16.82 for Hg/Cd, and 2.07 for Hg/Pb.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Hg-IIPs,Mercury,Removal[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
