Aim\ Prepare polymethacrylic acid chelating resins and study its adsorption in metalion. Methods\ Carboxylic chelating resins are prepared by polymerization of methacrylic acid with divinylbenzen as cross linker. The capacity of the chelating resins toward cupric ionic in aqueous media is studied by spectrophtometric method. Results\ Polymethacrylic acid adsorbance come up to 4.405 mg/g with Cu\+\{2+\}

Cu\+\{2+\} concentration drops from 1.0040 mg/mL to 0.029 27 mg/mL. Conclusion\ The exhibited high chelating capacity of the resins is significantly affected with the variation of pH value; when pH value was about 1

the capacity of polymethacrylic acid chelating resins was the highest.
