TREATMENT OF INDUSTRIAL WASTE WATER CONTAMINATED BY AROMATIC NITRO COMPOUNDS

Abstract

The work recorded in this thesis affords possibilities in techniques of waste immobilization utilizing pyrolysis of animal bones (Bone charcoal, BC) and Rice Husk (activated carbon, RHAC) as well as an opportunity to study a new technique, combination of adsorption and advanced oxidation process (AOP) to remove the nitro-organic compounds (e.g. trinitrotoluene (-TNT), dinitrotoluene (DNT) and nitrobenzene (NB) from industrial waste water obtained from a TNT manufacturing plant in Abu-Zaabal company for specialty chemicals The thesis is divided into three chapters Chapter 1 : An introduction describes a literature survey on the treatment methods for the remediation of nitro-organic compounds (e.g. chemical reduction, bioremediation, phytoremediation, adsorption and advanced oxidation process (AOP), also this chapter include theory of adsorption, mechanism of adsorption, adsorption isotherm, factors influencing adsorption (e.g. nature of the adsorbent, nature of the adsorbate, pH and temperature Chapter 2: The experimental part is given in this chapter where the physicochemical techniques used for preparation and characterization of the adsorbents “Bone charcoal (BC)” and “Activated carbon (RHAC)” in this study are given in order to gain better insight into the structure of RHAC and BC, infrared spectrometry, elemental analysis, and thermogravimetric analysis have been studied. The surface area of the AC and BC calculated from N2-gas adsorption using the BET-equation.
