Abstract:

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. T he 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 strength, and pH. Results revealed that the adsorption for compound at temperature of 25 ??C took: S- mode for MO, MB and MV while it was L-mode for SO according to Giles classification. 1- At temperature of 25 ??C the adsorbate arrange to the following order: MVMBSOMO 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 exothermic with distinction MB, MV there was absorption process too. 5- In comparison with zeolite (5A) the prepared polymer posse's higher ability to adsorbed MV, MO and SO while it was lower to MB.
