摘要：
In this study, we applied the modified cationic resin Amberlite (R) IRC-50 as a biopolymer adsorbent in the technique of adsorption of cationic dyes such as methyl blue (BM) and Safranin (SF) contained in wastewater models. During this technique, we studied the effects of the adsorbent dose and the neutral pH = 6.5 on the adsorption performance, knowing that the mass transfer mechanism was studied using a mass of 0.1 g of the adsorbent Amberlite (R) IRC50 and a concentration of 20 mg/L for the two colorants MB and SF. The results obtained with regard to the adsorption of these dyes from the present resin have shown that the modification of the surface of the cationic resin Amberlite (R) IRC-50 has a significant effect on the absorption and its increase has also shown that this process is more compatible with the pseudo-kinetics of the linear second degree model.
