The entire project is divided into six chapters. The content of the project presented in each chapter is given below. CHAPTER-I INTRODUCTION. Chapter I deals with the introduction and background history of various types of environmental pollution, particularly due to discharge of dyeing industry effluent. Review of literature on the removal of dyes using various adsorbents was also presented. CHAPTER-II SCOPE AND OBJECTIVES. Chapter II deals with literature survey of various low cost adsorbents uses for removal of dyes, scope and objectives of the present work. CHAPTER-III MATERIALS AND METHODS. This chapter deals with experimental procedure for the preparation of activated carbon from parthenium hysterophorous (L) and removal of two different dyes from the aqueous solution by adsorption methods. CHAPTER-IV RESULTS AND DISCUSSION PART-I ADSORBENT CHARACTERISTICS. This chapter discussed the results of the comparative physico chemical surface characteristics of the prepared of activated carbon. The XRD analysis depicts the presence of nano particles. The FTIR analysis depicts the presence of various functional groups.
