Abstract

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.

探索化学处理总形花可持续材料绿色吸附去除废水中亚甲基蓝染料的可行性

在这项工作中，以亚甲基蓝（MB）染料为试验用例，利用绿色技术，化学制备了总形藻（Lodh）生物废物（SR），使其成为一种可持续的材料，用于去除废水中的阳离子污染物。通过SEM、EDX、XRD、FTIR等方法观察了SR的形态变化。通过批量吸附实验，优化了MB染料的定制吸附解毒效果。实验的平衡数据与Langmuir等温线吻合最好，表明SR对MB的最大脱色能力（qmax）为10 mg/g。平衡数据的动力学建模符合准二级动力学，表明SR经过化学处理后孔隙度增强。可用于吸附去除阳离子污染物的可持续产品。图形抽象
