Removal of Zn2+ and Cr6+from waste water Samples, using natural Iranian (Aftar) Zeolites
<p>This paper concerns the removal of Zn<sup>2+</sup> and Cr<sup>6+</sup> ions from waste water using a naturally occurring zeolite from semnan region in Iran. A continuous fixed-column study was carried out by using zeolite as a low-cost adsorbent for the removal of Zn...
