Triethanolamine-glycerylmaleate polymer was prepared, and identified by FTIR spectroscopy then swelling tests were performed for this polymer in different solvents.The adsorption processes of the some phenols and acids compounds: ph, na, nal, B, AB and DAB in aqueous solutions on the surface of this polymer were investigated by the use of UVvisible spectrophotometer and also studied at different: temperatures,ionic strength,and pH.The results revealed that the adsorption for compound at temperature of 25 °C took: S-mode for all compounds according to Giles classification.1- At temperature of 25 C the adsorbate amount arrange to the following order:  
ph < nal <  na <  B <  AB  < DAB 2- The adsorption for ph, na, nal, and B take the following order for ionic strength 0.1M NaCl > 0.0M NaCl  >0.2M NaCl But for AB, and DAB take 0.0M NaCl > 0.1M NaCl  >0.2M NaCl 3- Generally   it   was   noticed   that   adsorption   quantities   is proportionally correlated with the pH studies.4- The ΔH values for all adsorbate compounds were negative,while ΔS values were negative for all compounds except for ph and B.5- In comparison with zeolite (5A) the prepared polymer posse’s higher ability to adsorb than zeolite especially for AB and DAB compounds.
