Sažetak

Wastewater from the textile industry contains large quantities of heavy metal ions such as Cr(VI), Zn(II), Pb(II) and Cd(II). They are often used for the production of color pigments for textile dyes. The free discharge of such waste water into the environment would cause major environmental problems. The presence of toxic Cr(VI) in the aquatic environment has been shown to be one of the major environmental problems. This article reports on the technical applicability of a low-cost green sorbent, nanoporous bentonite, as an adsorbent for the elimination of Cr(VI) ions from textile wastewater. The batch adsorption experiment was carried out to determine the influence of different working parameters (initial metal ion concentration, pH, amount of adsorbent) on the removal efficiency of Cr(VI). The experimental data were interpreted using the first and second order pseudokinetic model.
