    Adsorption of Hg2+ from aqueous solution onto polyacrylamide

    PAM can be successfully grafted onto KH-570-modified ATP using the solution polymerization method, for enhanced removal of Hg 2+ from aqueous solution. The adsorption capacity of Hg 2+ onto the PAM/ATP increases with increasing contact time and pH of the initial suspension, but decreases with adsorbent dosage.

    Adsorption of Hg2+ from aqueous solution onto polyacrylamide

    The increase in pH value of the initial solution has obvious positive effect on the linkage formation between the amide groups in the PAM and Pb 2+ in the solution and promotes the adsorption of

    Removal of Aqueous Hg(II) by Polyaniline: Sorption

    A polyaniline (PAN) prepared by chemical oxidation method was studied for Hg(II) removal from aqueous solutions. Batch adsorption results showed solution pH values had a major impact on mercury adsorption by this sorbent with optimal removal observed around pH 4−6. At both acidic and alkaline solutions beyond this optimal pH window, sorption capacity of PAN was substantially lowered, with

    After adsorption, HPACB was separated by centrifuge from aqueous solution and the residual concentration of Hg 2+ was measured with ICP-AES. Selective adsorption tests were also carried out as follows: HPACB (10 mg) was immersed into the mixed-ion solution (Hg 2+ , Cu 2+ , Cd 2+ , Co 2+ , Ni 2+ and Zn 2+ ) with pH 3.0 and initial concentration

    Selective adsorption of tannins over small polyphenols

    To mimic the selective removal or partial removal of tannins from beverage while remaining most of the health-beneficial low molecular weight polyphenols, adsorption of tannic acid, EGCG and catechin from their mixture in aqueous solution onto the polyacrylamide beads were performed and the results are shown Table 2. The adsorption capacities

    Adsorption Characteristics of Polyacrylamide and Sulfonate

    polymer solutions in the absence of adsorption, the polyacrylamide polymer (P AM) gave 178 cpm and the copolymer containing the sulfonate, P AMS, gave ISO cpm. When experiments were performed at 60°C, the procedure was slightly modified. The samples were equilibrated with the sodium kaolinite at 60° with shaking for 24 hr.

    The effectiveness of this sorbent towards the removal of divalent metal ions (Pb2+, Cd2+, Zn2+, Hg2+ and Cu2+), and organic contaminants (bisphenol A and ibuprofen) from aqueous solutions was investigated. The adsorption uptake of these pollutants onto MWCNT-ttpy was compared with that of acid-functionalized MWCNTs (MWCNT-COOH) to determine the
