Abstract:

Copolymer(Acrylamide-Bisacrylamide),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 some phenolic compounds: ph, DNPh, APh and NPh in aqueous solution on the surface of this polymer were investigated by the use of UV - visible spectrophotometer and also studied at different: PH, temperatures, and ionic strength. Results revealed that the adsorption for compounds at temperature of 25C? took: L - mode for ph, APh and NPh while it was S - mode for DNPh according to Giles classification. 1. at temperature of 25C? the adsorbate arranged in the following order:- APh DNPh NPh ph. 2.No deferent pattern was noticed with regard to the adsorption quantities according to the ionic strengths. 3. Generally it was noticed that adsorption quantities is proportionally correlated with the PH studies . 4. The adsorption for all compounds was endothermic .5. comparison the adsorption of compounds ( Ph, DNPh , NPh , APh ) on other standardization adsorption surface such , Zeolite and porous carbon , showed that only Ph adsorption on polymer surface was greater than on Zeolite and Carbon, while other compounds showed different adsorption ability on this adsorption surfaces .
