ABSTRACT

ABSTRACT: Perchlorates are highly soluble anions and are used as ingredients in solid rocket fuels, fireworks, missiles, batteries etc. The potential human risk of perchlorate exposures includes effects on nervous system, inhibition of thyroid activity and mental retardation in infants. Various materials and techniques have been used to remove perchlorate from drinking water. For light polluted water of perchlorate, adsorption seems to be one of the most attractive, easiest, safest and cost effective physio-chemical treatment methods especially for drinking water. Rice husk, one of the major bi-products of rice milling industry can be used as a low cost adsorbent for perchlorate removal.
