عنوان انگلیسی Modified Biopolymer as Adsorbent for Methylene Blue Dye Removal
چکیده انگلیسی مقاله In this work, we developed an eco-friendly material to apply in the wastewater treatment operation. This copolymer was prepared from carboxymethylcellulose (CMC) modified with acrylamide (AM) and N-vinylpyrrolidone (NVP). It w:as char:acterized using FTIR spectrometry, Thermogravimetric Analysis (TGA/DTG) and diffraction of X-ray (XRD). CMC-AM-NVP copolymer properties as an adsorbent of methylene blue (MB) dye were investigated. Influencing parameters on the removal process were also studied. It was found that the adsorption of MB dye on CMC-AM-NVP copolymer can be described by the pseudo-second order equation. Equilibrium data was modeled by Langmuir, Freundlich, and Temkin isotherms. Langmuir isotherm model provides the best fit to represent the adsorption of MB on the CMC-AM-NVP copolymer within R2 equal 0.999. The dye elimination efficiency on the copolymer reached 99.4%.
According to these tests, CMC-AM-NVP was found to be promising candidates for efficient removal of methylene blue; therefore, we can conclude that the addition of NVP to the copolymer has a clear improvement in the adsorption process.
