Sažetak
This study was focused on waste quartz material as an alternative adsorbent for the removal of Cr (VI) ions from aqueous solutions .Waste quartz material originates from mechanical treatment of quartz discs for CVD equipment. The adsorption process was monitored by various contact time adsorbent – adsorbat. The obtained results show that the waste quartz material was very good adsorbent for removal Cr (VI) from aqueous solution. A comparison of kinetic models applied to the adsorption of Cr (VI) ions on the waste quartz material was evaluated by the pseudo first-order, the pseudo second-order, Elovich, intraparticle diffusion kinetic model and mass transfer model. The results show that the pseudo second-order kinetic model best described the adsorption of Cr (VI) on waste quartz material.
