This study involves preparations of polymers poly (styrene -co-acrylic) and poly (styrene -co-methyl methacrylate) via free radical polymerization at temperatures between (70 and 80 °C) with conversion rates of 10% for initiator benzoyl peroxide. Through neutralizing polymer with hydroxyl amine hydro-chloride in a base medium pH = 12–13 utilizing potassium hydroxide (KOH) with the thermal escalation for 120 hrs, the ester group in the resulting polymers have been converted to poly hydroxamic acid (HA). The resulting compound has then been identified through infra-red spectroscopy (FT-IR) and NMR. Magnesium oxide-nano was mixed thoroughly with the corresponding amount of poly HA. Prior to and following the addition of Magnesium oxide - nano to poly (styrene -Co- methyl metha acrylic) HA, the adsorption capacity regarding the ferric and vanadium ions was evaluated. Effects of temperature, time, and PH on the capacity of the adsorption have been investigated. The rate of adsorption reduces as acidity rises and falls from pH=6, and adsorption heat has been calculated at 2 temperature degrees. The capacity for adsorption increases with the increase in time, and the maximum adsorption capacity has been at pH = 6. According to values of the adsorption temperature, ferric ion adsorption is physical whereas vanadium ion adsorption is chemical.
