          Orange peels are a promising agro industry-waste that can be implemented in the extraction and production of pectin, as dietary fiber in food formulations, and as a biopolymer for metal adsorption in water treatment. In the present work, the adsorption behavior of methylene blue (MB) and erichrome black T (EBT) dyes by using cheap and eco-friendly orange peels which was chemically modified by sodium hydroxide (NaOH) and a cetyltrimethyl ammonium bromide (CTAB) have been studied.

                The computational chemistry in recent years becomes of great importance in many chemical and pharmaceutical scientific fields.This thesis involves a theoretical study for compounds contain four
saturated diazabicyclo molecules with the presence of two atoms of nitroges (N-N) as a bridgehead. These molecules are 1,3diazabicyclo[1.1.0]butane (DABCB), 1,4-diazabicyclo[2.1.0]pentane

   Aluminium metal processing is only feasible at high temperature like extraction by electrochemical process from its ores at high temperature.Such process are not feasible in aqueous liquids due to production of hydrogen (-0.8V) much prior to aluminium electroreduction (-1.65V).Other solvents such as organic and ionic liquids have their setbacks for many practical, economic and environmental reasons.
