Exploring chemically processed Symplocos racemosa sustainable material feasibility for sorptive amputation of methylene blue dye from waste water by green technology

In this work, Symplocos racemosa (Lodh) biowaste (SR) was chemically fabricated to make it a sustainable material for detoxifying cationic pollutants from waste-water by green technology using methylene blue (MB) dye as a test case. Morphological changes that occurred in SR were observed by SEM, EDX, XRD, and FTIR methods. Batch adsorption experiments were conducted to optimize tailored adsorptive detoxification of the MB dye. The equilibrium data of experiments was found to be in best fit with Langmuir isotherm, showing that the maximum dye removal capacity of SR (q_max) was 10 mg/g for MB. Kinetic modeling of equilibrium data followed pseudo-second-order kinetics, indicating enhanced porosity after chemical processing of SR. The results confirmed the prospective application of Symplocos racemosa lignocellulosic waste as a natural, cheap, and sustainable product that can be used for adsorptive removal of cationic pollutants.
