          The present thesis consists of four chapters that throws the light on studying the corrosion behavior of`α-brass in the acidic media using the potentiostatic polarization. Each chapter discusses many topics can be demonstrated as following:
1. Chapter one discusses the introduction topics about corrosion, corrosion forms, electrochemical aspects and copper alloys.  
2. Chapter two discusses the experimental procedures and techniques about characterization of the pomegranate and red apple peels and the polarization study.

In this study, Heterocyclic  Compounds were synthesized by several steps as following:

First step: the 1-[4-(5-Bromo-pentyloxy)-phenyl]-ethanone (B1) was synthesized by treatment of    4-hydroxyacetophenon (A) with 1,5-dibromo pentane  in presence of  anhydrous potassium carbonate and acetone.

Filtration of waste water accompanied with the oil from the well during the refining process, represents a real problem at some case since it may be the source of bacterial growth.Here in this project, MgO nanoparticles has been prepared by sol- gel method to produce particles with sizes range (40nm), while Ag nanoparticles has been prepared by simple chemical method with sizes range (50.73nm).
