Abstract

Herein, fabrication of a novel eco-friendly and effective biosorbent (SCB-GO-PAA) nanocomposite were investigated by modification of sugarcane bagasse (SCB) as lignocellulosic biomass with graphene oxide (GO) and polyacrylic acid (PAA) using homogenizer as a new technique to prepare (SCB-GO-PAA) nanocomposite. The fabricated materials were characterized using SEM, FTIR, TGA, and XRD, and were tested to adsorb methylene blue (MB) dye from aqueous solution. Adsorption parameters were studied to investigate the optimum conditions that achieve the higher adsorption capacity. The adsorption processes were carried out according to Langmuir isothermal model and pseudo-second-order kinetic model with maximum sorption capacity of MB-dye by SCB, SCB-GO, and SCB-GO-PAA nanocomposite of 143.56, 265.85, and 543.28 mgg<superscript>−1</superscript>, respectively. The results revealed that the fabricated biosorbents are promising materials with considerable adsorption capacity comparing to other novel adsorbents. Also, this eco-friendly and effective bioadsorbent can be utilized on large scale to remove MB-dye from various types of wastewater. [ABSTRACT FROM AUTHOR]
