Poly(sodium 4-styrenesulfonate)-metal ion interactions

Abstract

ABSTRACT:The metal ion-binding properties of poly(sodium 4-styrenesulfonate) in conjunction with membrane filtration were investigated for Cu(II), Cd(II), Co(II), Cr(III), Hg(II), Ni(II), Pb(II), Zn(II), and Fe(II). Different experiments were carried out at different pH's, metal ion concentrations, polymer concentrations, and molecular weight fractions. Only Fe(II) and Cr(III) were retained at pH 1, which allows a selective separation of these metals from all the other metal ions. At pH 3 the retention ability of this polymer increased for all the metal ions. On the other hand, the metal ionretention properties are dependent on the polymer/metal ratio.

One-Pot Reaction Involving Two Different Amines and Formaldehyde Leading to the Formation of Poly(Macrocyclic) Cu(II) Complexes

“…In this work, we successfully prepared the poly(hexaaza macrocyclic) copper(II) complexes [1] 2n+ , [2] 2n+ , and [3] 2n+ from the one-pot reaction of Eqs. (2) and (3).…”

“…In the spectra of [2] Fig. 1(c)) and [3] (Fig. 1(d)), a sharp peak corresponding to ν N-H of the secondary amino groups is observed at ca.…”

SYNTHESIS AND CHARACTERIZATION OF POLY([(2-methacryloyloxy) ethyl]) TRIMETHYLAMONNIUM CHLORIDE) RESIN WITH REMOVAL PROPERTIES FOR VANADIUM(V) AND MOLYBDENUM(VI)

“…The treatment of heavy metals is of special concern due to their recalcitrance and persistence in the environment. In recent years, various methods for heavy metal removal from wastewater have been extensively studied [2][3][4][5][6][7][8][9]. These technologies include chemical precipitation, ion exchange, adsorption, membrane filtration, coagulation-flocculation, flotation and electrochemical methods.…”

Controlled exchange of metallic cations by polypyrrole-based resins

“…Finally, some qualitative results will be collected about the fixation selectivity in a mixture of two cations of different charge [6].…”
