| Abstract | ||
| The aim of this research is the preparation of Poly (Methyl methacrylate –co- Methylacrylate) by a free radical initiating process for co-polymerization between methylmethacrylate and methyacrylate with amixing ratio (1:1), using benzoyl peroxide as an intiator at (70°C ) and(10%) ratio of conversion. Conversion of the ester group of the (CPMMA-MA) in to Hydroxamicacid was carried out by treatment of (CPMMA-MA) with hydroxylaminehydrochloride in alkaline medium at (pH=13) using Sodium Hydroxide. The poly hydroxamic acid was identified by (FT-IR) spectroscopy. Adsorption Capacity (qe) of the metal ions (Fe3+ ) and (Cu2+ ) using (PHA) was determined . Also the study showed that there was an effect of initial (pH ) and temperature on the adsorption capacity of (Fe3+ ) and (Cu2+ ) . Langmuir and Freundlich equation models were used to describe the equilibrium Sorption Isotherms , using different concentrations solution of (Fe3+ ) and (Cu2+ ) at pH=4 and 25°c by poly hydroxamic acid. | ||
