ABSTRACT : Over the last few decades, the occurrence of micropollutants in the aquatic environment has become a worldwide issue of increasing environmental concern. Micro pollutants are the variety of different substances which have adverse environmental effects. these emerging polltants are found in very low concentrations, by the micro or nanogram/L in aqueous systems. Adherence to substance : Diclofenac is a nonsteroidal anti-inflammatory drug. This medicine is use for reducing pain and inflammation in the body. It is one of the most frequently detected pharmaceuticals in the aquatic environment. Because of its low biodegradability and its limited sorption properties onto activated sludge, diclofenac is considered to be one of the most relevant compounds in terms of ecotoxicity and persistence in the environment. The present investigation aims to exploit the hectorite clay as to obtain the novel hybrid materials using the CTAB as organic modifier to form CTAB modified organo-hectorite clay. The modified materials possess hydrophobic core, perhaps, provide an efficient partitioning of organic contaminants diclophenac removal from aqueous solutions even at low level concentration. In addition, the study could contribute to the pharmaceutical industry by eliminating waste water drainage away an diclofenac.
