Preparation and Manufacture of Some Composite Materials and Study of their Use in Water Purification from Organic Compounds and Heavy Metallic Elements

Abstract

In this research ,the composite materials were prepared and manufactured in several stages ,including the first stage the preparation of poly methyl methacrylate , using the polymerization of free radicals by the initiator Benzoyl Peroxide at a temperature (70oC) and a conversion rate of 10%, and then converting the resulting polymer to Polyhydroxamic acid by treating the polymer with Hydroxylamine Hydrochloride in an alkaline medium (pH = 13) with the use of Potassium Hydroxide with thermal escalation at a temperature of (70oC) for a period of (100) hours. The resulting compound was diagnosed using IR-FT spectroscopy, Polyhydroxyamic acid was mixed with Nano Carbons. The adsorption Capacity of some heavy metal ions from their aqueous solutions, such as (Fe3+, Cu2+,Ni2+,Co2+, Cr2+,V3+,Pb2+ and Cd2+) ions by composite materials before and addition of Nano – Carbon , was determined . Also the Study of the adsorption capacity of Acetic Acid and Oxalic acid Oxalic acid on Polyhydroxyamic Acid before and after treatment with Nano Carbon. study showed the adsorption capacity values were very low or almost non-existent with Polyhydroxamic acid. While there was a significant increase in the values of adsorption capacity of Acetic Acid and Oxalic Acid of Polyhydroxyamic Acid treated with Nano Carbon and camping in the following results.
