Cellulose Based Adsorbent for Cationic Methylene Blue Dye Removal

Abstract

Abstract New chemically amended (sodium periodate cellulose nanoparticle (NaIO4-CNP) adsorbent material was synthesized from dried fibers of cotton. The synthesized NaIO4-CNP adsorbent material was characterized for functional groups, crystallite size, surface morphology, morphological structure, and particle size) by using Fourier transform infrared (FT-IR), X ray diffraction (XRD), Scanning electron microscope (SEM), Transmission electron microscope (TEM) and Brunauer Emmett Teller (BET), instruments, respectively. Then it was investigated to eliminate methylene blue (MB) dye from textile secondary runoff wastewater (SERWW). The physicochemical properties of textile SERWW including organic matter (OM) and inorganic nutrients on the removal capabilities of MB dye was investigated. The adsorption mechanism study was shown that Freundlich isotherm fitted with a maximum removal capability (qmax) of 62.91 mg g−1. The elimination kinetic mechanism fits well to pseudo-second-order and its data recommended the materials (NaIO4-CNP) are effective for wastewater treatment. The MB dye uptake capacities were influenced by the presence of positively charged ions. The NaIO4-CNP adsorbent indicated excellent reproducibility considered as capable adsorption resources to eliminate MB dye from textile SERWW.
