Surfactant modified barley straw for removal of acid and reactive dyes from aqueous solution
چکیده انگلیسی

A barley straw was modified by a surfactant, cetylpyridinium chloride, and used as an adsorbent for acid (acid blue 40) and reactive dye (reactive black 5) adsorption in aqueous solution. Characterization of the modified barley straw was performed using N2 adsorption, titration, and FT-IR analysis. It was found that the surfactant modified barley straw exhibits higher adsorption to acid blue 40 than reactive black 5 and adsorption of the dyes is influenced by several parameters such as dye initial concentration, adsorbent dosage, solution pH, and adsorption temperature. Adsorption isotherms show that maximum adsorption of acid blue 40 and reactive black 5 is 1.02 × 10−4 and 2.54 × 10−5 mol/g, respectively. Desorption studies show that both dyes are strongly bounded with the adsorbent and exhibit low desorption.
