Development of Functional Adsorbent From Textile Cotton Waste by Radiation Induced Grafting Process: Equilibrium and Kinetic Studies of Acid Dye Adsorption

Abstract

An environment benign-aqueous solvent based-single stepradiation induced grafting process was used to graft Poly(vinylbenzyltrimethyl ammonium) chloride (PVBT) onto cellulosic cotton textile waste to transform it into a valuable cationic adsorbent (PVBT-g-Cellulose). The PVBT-g-Cellulose adsorbent was characterized by grafting yield determination, elemental analysis, scanning electron microscope (SEM), and fourier transformed infrared (FTIR) spectroscopy. The PVBT-g-Cellulose adsorbent, investigated for the removal of model dyes from manufactured solutions, exhibited equilibrium adsorption capacities of $540 mg/g, $474 mg/g, and $122 mg/g for acid blue 25(AB25), acid yellow 99(AY99), and acid blue 74(AB74), respectively. The degree of agreement between the adsorption isotherm models and experimental data followed the order: Langmuir-Freundlich>Redlich-Peterson> Langmuir>Freundlich. The kinetic adsorption data was found to be in close agreement with pseudo-second order kinetic model. The elution percentage of as high as $95% could be achieved for AB25 using a suitable eluent.

Adsorption of toxic acidic dye from aqueous solution onto diethylenetriamine functionalized magnetic glycidyl methacrylate-N,N′-methylenebisacrylamide

“…A direct comparison of sorption performance is difficult due to different experimental conditions; however, this is a useful criterion for roughly evaluating the potential of these materials. The MGMA-DETA adsorbent has a adsorption capacity of the same order of magnitude as other sorbents; although cotton cellulose based cationic adsorbent, 35 Stipa Tenacessima L cationized bers, 37 cationized sawdust 39 and polyacrylonitrile/activated carbon composite 40 showed better adsorption capacity. When taking into account only the organic compartment in the MGMA-DETA that represents about 77% of total sorbent mass, the sorption capacity of MGMA-DETA increases to 0.298.…”

“…factor on the implementation of such technology (Kumar et al 2012;Saxena et al 2017;Schwantes et al 2016;Senthil Kumar et al 2012). As a result, a growing interest has been directed to utilizing naturally available materials for adsorption applications (Ab Razak et al 2015;Abdelrazak et al 2017;Abdolali et al 2015;Schwantes et al Schwantes 2016).…”
