         Triethanolamine – glycerol maleate polymer was prepared,and identified by F.T.I.R. spectroscopy then swelling tests were performed for this polymer in different solvents.The adsorption processes of the some dyes compounds: MO,MB, MV and SO in aqueous solutions on the surface of this polymer were investigated by the use of UV–visible spectrophotometry and also studied at different: temperatures, ionic

This work represented a contribution to draw attention towards the amount of metals in Basra and Kirkuk crude oil blends. These metals may effect the processing refineries of crud oils.   In chapter one of this thesis, an introduction was given on the crude oil and it^'s origin including both inorganic and organic theories; also the composition and types of crude oil, the importance and the problems associated with the presence of the metals. Finally, the methods used for the determination of metals were given.

         The current study involves the preparation of number of urea derivatives from reaction of urea or thiourea with aromatic amines as in compounds:"Phenylthiourea, N-phenylurea, N-(2-methoxyphenyl) urea, N-(4-aminophenyl) urea, N-(2-methylphenyl) urea, N-(2-methoxyphenyl) thiourea, N-[4- (amino carbonyl) amino phenyl] urea, N-[4-(amino carbonyl) amino phenyl] acetamide, N-pyrazin-2-ylurea, N-pyridin-2-ylurea, N,N^´-bis(3-bromophenyl)urea, N,N^´-bis(2-methoxyphenyl)urea ".In addition to the preparation of three compounds
