Study of the behavior of strontium adsorption on PAN-Zeolite A composite adsorbent

Composite adsorbent was prepared and tested for its ability to remove Sr2+ ions from aqueous solutions. The composite was prepared by mixing synthesis zeolite A with polyacrylonitrile (PAN) solution as a binder. Optimal conditions for composite preparation such as mixing ratio of zeolite and PAN, mixing time and temperature were determined. The physico-chemical properties of these composites were determined using some instrumental analysis viz. XRD, XRF, FT-IR, BET and DTG. The composite adsorbent was treated with Sr (NO3)2 solution to determine its sorption capacity. All Sr2+ measurement were carried out by ICP-AES. Kd value was determined and was found to be 1.1×104 ml g-1. These results have shown that composite adsorbent could be effectively used for adsorption and removal of strontium ion from aqueous solution.
