preparation and characterization of some novel chelating resins based on waste materials for water treatment

Abstract

Water sanctity throughout history where the creation of every living thing was obtained, but with the progress of civilization of mankind water pollution has become one of the negatives of this progress. So scientists have been working to find out solutions for water purification. The heavy metals are the most dangerous pollutants facing organisms because of their toxicity. Various technologies have been developed to be available for removal of toxic materials from waste water, thereby preventing the pollution of surface and ground water. The current study take care of a solution to the problem of environmental pollution and re-plastic waste recycling for water pollution treatment. Hence a new easily prepared, low-cost and efficient chelating polymers CPs based on waste polystyrene plastics (PSt) and polymethylamethacrylate PMMA functionalized by itaconic acid (IA) and 2-hydroxyethyl methacrylate (HEMA) moieties in absence and presence of montmorillonite clay MMT have been used as potential adsorbents for removal of toxic heavy metal pollutants from water system. The adsorption of Cu2+ ions were found to be time dependent. Adsorption isotherms have been 145 studied in terms of Langmuir, Freundlish and Temkin isotherms models. The values of correlation coefficients deduced from the aforementioned three models confirmed that R1, R3, R4, R5, R6 and R7 are good fitted to Temkin adsorption model. In the other hand, R2 and R8 follows
