In concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. The purpose of this article is separation of chromium and magnesium cations from 35wt% commercial hydrogen peroxide solution by ion exchange method with strong acid cation resin Amberlite IR-120 H+ with styrene divinylbenzene copolymer network and sulfunic acid functional group. In separation of chromium and magnesium, we used batch system and tank equipped with mixer. Effect of the amount of resin and contact time on the separation of cation is investigated. The metal ion concentration in the original solution and the metal ions left unsorbed were determined by Inductively coupled plasma spectrometry (Varian Vista ICP–AES) technique. In determining the effect of the amount of resin and contact time on separation of cation, amount of chromium and magnesium in hydrogen peroxide solution was 0.1 mg/mL, 0.3 mg/mL and 0.5 mg/mL. Experimental results obtained from the separation of chromium and magnesium compared with Freundlich, Langmuir and Jovanovic adsorption isothermal models. Results show that these models only in a certain range of concentration, are consistent with experimental results.
