Use of Fly Ash as Adsorbent for Removal of Chromium from Aqueous Solution

Water pollution is cause due to toxic heavy metals that has become a major cause of concern for environmental engineers. Cr (VI) is a highly toxic metal ion and considered a priority pollutant released from various industries. Adsorption is one of the effective techniques for chromium (VI) removal from wastewater. In the present study, fly ash is used as an adsorbent for removal of Cr (VI) from aqueous solutions. Fly ash samples were collected from the Kota Super Thermal Power Station, Kota (Rajasthan). Physico ???????? chemical analysis were performed of collected fly ash samples. Batch adsorption studies were carried out systematically. Different parameters such as initial metal ion concentration, adsorbent doses, pH and contact time were studied.
