Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -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 UV-visible 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 H values for all adsorbate compounds were negative, while S values were negative for all compounds except for ph and B. 5- In comparison with zeolite (5A) the prepared polymer posse s 92 pp. Englisch.
