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

1.   at temperature of 25C˚ took: L – mode for ph, APh and NPh while it was S – mode for DNPh according to Giles classification.at temperature of 25C˚ the adsorbate arranged in the following order:-      APh > DNPh > NPh > ph.

  1. 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 .
