In this study comparison for wastewater treatment takes place between Corn Straw [CS] waste and MicroCrystalline Cellulose [MCC] as two different reasonably priced biomass subjected to graft via acrylic acid. The grafting polymerization for two biomass individually and Acrylic Acid [AA] done via ammonium persulfate as initiatore and N,N-methylenebisacry lamide as crosslinking agent , to concoct CS-g-AA&MCC-g-AA . The structure and properties of the resulting product characterized by Add On percent, FTIR, X-ray diffraction, SEM. The grafting conditions studied and the final product subjected to adsorption study.

The results of the adsorption study revealed that grafting PAA onto MCC even at the lowest concentration improved the adsorption efficacy significantly. The optimum conditions for the removal of RhB are pH 6, and 1.0 g/L where 93% was removed in 90 min using MCC-g-PAA0.5 and 90% was removed in 90 min using CS-g-AA4. The adsorption kinetics and isotherm studies illustrated that the adsorption process wasn't simple. Comparing the Langmuir theoretical monolayer saturation capacity of CS-g-AA4 (233 mg/g) showed its high potentiality as adsorbent for the treatment of dye-contaminated wastewater.
