Removal of some Pollutants in Waste Water The Role of Radiation and Polymeric Materials in the

Abstract

All sUrface waters should be of adequate quality to support aquatic life and be aesthetically pleasing. Wastewater containing toxic pollutants poses a serious environmental problem. Many of the pollutants are not readily biodegradable and complete removal in many cases is relatively expensive process. On the other hands, incomplete removal is serious health hazard. The efficiency of ionizing radiation techniques for degradation of many organic compounds and precipitation of heavy metals was verified and •proved to be more effective than ordinary conventional methods. In the present study a try was made to explain the degradation kinetics due to irradiation of aqueous solutions of some pollutants in the absence of other specific pollutants.

Five pesticide and four heavy metals elements were used as pollutants in water through the present work. One carbamate insecticide, lannate, one phenyl acetate group of insecticide, fenvalerate, one acetyl alaninate group of fungicide, metaloxyl, one nitroaniline group of fungicide, dicloran and one phenyl urea group of herbicide, arelen. Also, four heavy metals, copper sulphate, lead acetate, cobalt chloride and nickel chloride were
