         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
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 25C the adsorbate arrange to the following  order:MV>MB>SO>MO
  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 istinction 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.
