Dyestuffs removal from synthetic wastewater with chitosan,cross-linked chitosan and chitosan-poly (acrylic acid) conjugate

Remazol brillant blue r (rbbr) and naphthol blue black (nbb) dyestuffs are commonly utilized in the textile industry. in this study,rbbr and nbb dyestuffs were removed with chitosan,cross-linked chitosan and chitosan-poly(acrylic acid) (paa) conjugate. cross-linked chitosan and chitosan-poly(acrylic acid) conjugate were synthesized at 15 and 30 minutes respectively by using microwave energy. rbbr dyestuff was removed 70.23 % and 80.78 % at ph: 4.0 and ph: 5.0 respectively by chitosan-poly(acrylic acid) conjugate. nbb and rbbr were removed higher percent with crosslinked chitosan than chitosan-poly(acrylic acid) conjugate at acidic phs. nbb and rbbr were removed successfully with approximately 100 % dye removal percentage using both chitosan and cross-linked chitosan.
