摘要:The purpose of this study was to find a relatively inexpensive method for
removal of arsenate and arsenite from drinking water. The capability of Iranian
natural clinoptilolites, relevant synthetic zeolites A and P and Iron(П)
modified of them was investigated for the uptake of arsenic anions from drinking
water. Data obtained from ion-exchange using batch (static) technique showed
that among the investigated zeolites, modified synthetic zeolite A was the most
selective sorbent for removal of arsenic. In this study, the influence of
factores including temperature, arsenic concentration, pH and zeolite particle
size on removal of arsenic species from water was also determined and studied.
