摘要: In the presented paper, ability of commercially available gel and macroporous polystyrene anion exchangers for removal copper(II), zinc(II), nickel(II), cadmium(II) complexes with 1-hydroxyethane-1,1-diphosphonic acid (HEDP) from aqueous solutions was investigated under various experimental conditions. experiments, strongly basic Lewatit MonoPlus M 600, MP 500, Amberlite IRA 402 quaternary ammonium functional groups as well medium exchanger 64 ammonium/tertiary amine were used. Special attention paid to concentration heavy metal ions, M(II)−HEDP molar ratio, pH solutions, temperature, physicochemical properties The effect interfered ions such Ca(II), Mg(II), Cl−, NO3−, SO42− on efficiency HEDP sorption also investigated. It found that anion...
