It was applied as a new adsorbent for removal of methyl green (MG) dye. The effects of different significant parameters, such as pH solution (2-10), adsorbent dosage (0.005, 0.01 and 0.02 g) and contact time (0 – 120 min) were explored. Results show that the adsorption process was depended on pH solution. The highest adsorption capacity of EP-CS-SB was obtained 98.47% at pH =8, 120 min, and 0.02 g of EP-CS-SB. EP-CS-SB was found to be a suitable candidate for removal of cationic dye.}, keywords = {Epichlorohydrin,Cinnamaldehyde,Chitosan Schiff base,Methyl green removal}, url = {https://www.ajnanomat.com/article_135684.html}, eprint = {https://www.ajnanomat.com/article_135684_6921b14b4ba386abec34a2b63ba1d6fd.pdf} }
