Removal of Metal ions from Industrial Wastewater by photocatalysis

Abstract

1- General introduction, which gives a brief background on the problem of water shortage in Egypt and environmental impact of wastewater contaminated with heavy metals. In addition, the advantage of heterogeneous photocatalysis. Finally, this chapter contains also the objectives adopted for this study. 2- Comprises the literature survey on: environmental impact of heavy metals. Conventional method of treatment for heavy metals. The basic mechanism of photocatalytic process.
