چکیده
|
This paper concerned the removal of zn2+ and cr6+ 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 zn2+ and cr6+ ions from aqueous solution under the effect of various process parameters such as, grain size and time. the efficiency of removal was higher for zn than cr ions. the zn2+ and cr6+ ions uptake by zeolite increased with initial ions concentration and column height, but decreased as the flow rate increased. the adsorption capacity reached a maximum at grain size of 0.71mm
