In the present work we investigated the adsorption processes of Ca(II), Ag(I) and Pb(II) in aqueous solution on sulfonato modified silica prepared from rice hull ash.. as the

Pb-IIP was synthesized through 4 reaction stages (Scheme 1), namely: 1) grafting of chloroacetic on chitosan (CMC), 2) adsorption of Pb(II) ion on CMC (CMC-Pb), 3) Cross-linking

chloroacetic acid grafting and cross-linking has been proven to increase the adsorption of pec-CMC-BADGE adsorbent toward Pb(II) ion. In Table 1, G° value for adsorption of Pb(II)

The experimental data for the adsorption of Acid Blue 129 dye from aqueous solution onto bentonite and its modified form were correlated using the Langmuir, Freundlich, Sips and

duplicatum biomass immobilized on silica gel, it was performed the adsorption competition of Cu II, Cd II and Pb II ion in multi-metal solution at the optimum conditions of the

The linear form of the Freundlich adsorption of isotherm Mn2+ by freeze-dried penneri 2120 maximum adsorption capacity dried biomass of the isolate 2120 for removal of Mn2+ ions The
