The HE-3B-anchored membranes from their single solutions were 6.4 mmol/m(2) for Cu(II), 30.1 mmol/m(2) for As(III), 76.3 mmol/m(2) for Cd(II) and 130.3 mmol/m(2) for Hg(II). When the heavy metal ions competed tin the case of the adsorption from their mixture) the adsorption capacities were 7.8 mmol/m(2) fur Cu(II), 24.5 mmol/m(2) for As(III), 27.6 mmol/m(2) for Cd(II) and 42.3 mmol/m2 for Hg(II). The same affinity order was observed under non-competitive and competitive adsorption which was as follows: Hg(II) > Cd(II) > As(III) > Cu(IT). The adsorption of heavy metal ions increased with increasing pH and reached a plateau value at around pH 5.0. Heavy metal ion adsorption from artificial wastewater was also studied. The adsorption capacities are 4.1 mmol/m(2) for Cu(II), 12.5 mmol/m(2) for As(III), 16.7 mmol/m(2) for Cd(II) and 21.3 mmol/m(2) for Hg(II). Desorption of heavy metal ions was achieved using 0.1 M HNO3. The Procion Red HE-3B-anchored membranes are suitable for repeated use for more than 5 cycles without noticeable loss of capacity.eninfo:eu-repo/semantics/closedAccessProcion Red HE-3Bpoly(HEMA) membranesheavy metal removalcopper(II)arsenic(III)cadmium(II)mercury(II)Dye affinity poly(2-hydroxyethyl methacrylate) membranes for removal of heavy metal ionsArticle37434335610.1081/MA-1001010972-s2.0-0000744530Q2WOS:000086380400003Q2
