          Five metal ion complexes of Ni(II), Cu(II), Zn(II), Cd(II) and Sn(II) with potassium 2-(4-isobutylphenyl) propanoate, as a ligand (L) has been prepared in alcoholic medium.
These complexes are:
Bis2-(4-isobutylphenyl) propanoato  Nickel(II), NiL2
Bis2-(4-isobutylphenyl) propanoato  Cupper(II), CuL2
Bis2-(4-isobutylphenyl) propanoato  Zinc(II), ZnL2
Bis2-(4-isobutylphenyl) propanoato  Cadmium(II), CdL2
Bis2-(4-isobutylphenyl) propanoato  Tin(II), SnL2

          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
