This study presents Pb(II) recovery/removal from water solutions using two different commercial ion-exchange resins, i.e., Dowex G-26 with sulfonic functional group and Puromet™ MTS9570 phosphonic groups. Overall, 100% by both resins was obtained at solution pH 3.5, resin dosage 25 g/L, adsorption time 30 min, room temperature, initial concentration 1000 mg/L. Langmuir, Freundlich, Temkin isoth...

the polymer supported hypochlorite ion is a facile selective oxidizing agent for the oxidation of various alcohols to aldehydes and ketones. similarly is successfully oxidizes various hantzsch type 1,4- dihydropyridines to corresponding pyridines.

The performance of anionic exchange resin Dowex 1x8 in the removal arsenic(V) from aqueous solutions was investigated. Batch experimentation carried out under different variables, including, stirring speed applied on system, pH solution, dosage and temperature. Due to characteristic speciation phases, this element solution is negligible at highly acidic or alkaline values, but it possible range...
