Phyco-Sorption of Uranium from its Different Processing Effluents

Abstract

This work is a good and promising trial for the removal and recovery of uranium using algal biomasses as one of the most effective eco-friendly techniques. These divided mainly to four chapters;

Chapter I: Introduction

This part gave brief introduction about the identification and importance of algae. In addition to their application and uses in the human life, specially their role in the biosorption of heavy metals and radio nuclides. Also, waste water sources and management, uranium as one of the most valuable elements, uranium processing, and the resulted effluents from these processes. As well as, how the uranium release to environment and its threat effect. Finally a short discussion about the statement of the water shortage problem was discussed.

Chapter II: Literature Survey

This chapter surveys several topics, namely uranium resources in Egypt, the uranium processing and how the uranium effluents were produced. In contrast, surveying the role of biotechnology in uranium processing, such as bioleaching and biosorption was investigated and the mechanism of biosorption process. Finally special survey on the biosorption of heavy metals and uranium was carried out.

In the end of this part the two targets of this study were stated as recovery of uranium during its processing using an economical and eco-friendly technique (phyco-sorption) and concentration on the purification of wastewater resulting in uranium processing of Gattar Pilot Plant (Nuclear Materials Authority) from heavy metals and other impurities to can be recycled again in the leaching process to achieve water saving.
