摘要

本研究采用一步黄腐法从柿子叶(Diospyros kaki)中合成生物吸附剂。合成的生物吸附剂(简称 MPM)在不同的 pH 值下对六价铬和镉(II)具有很高的吸附能力。具体来说,在 pH 值为 3 时,Cr(VI)-MPM 的朗缪尔最大吸附容量为 710 毫克/克,而在 pH 值为 7 时,Cd(II)-MPM 系统的吸附容量为 622 毫克/克。两种金属离子的吸附动力学都遵循伪 2 阶模型,R2 值接近 1(0.99)。通过 FT-IR 和 XPS 研究,可以确定离子交换、表面络合和螯合是使用 MPM 作为吸附剂从水中去除分析物的主要机制。MPM 中的 -CS2-Na 基团在这些去除机制中发挥了关键作用。此外,MPM 对金黄色葡萄球菌和大肠杆菌具有显著的抗菌效果。考虑到 MPM 快速的动力学特性、广泛的 pH 适用范围、惊人的吸附能力、可回收性和有效的抗菌特性,MPM 被证明是一种非常适合去除工业废水中六价铬和镉(II)的吸附剂。

Synthesis, characterization and application of xanthated Diospyros kaki (persimmon) leaves for the treatment of chemical and biological contaminants in aqueous solutions

In this research, a one-step xanthation process was used to synthesize biosorbents from persimmon leaves (Diospyros kaki). The resulting biosorbents, referred to as MPM, exhibited high sorption capacities for Hexavalent chromium and Cd(II) at different pH values. Specifically, at pH 3, the Langmuir maximum adsorption capacity for Cr(VI)-MPM was determined to be 710 mg/g, while at pH 7, it was 622 mg/g for Cd(II)-MPM systems. The adsorption kinetics of both the metal ions followed the pseudo-2nd-order model, with R2 values close to 1 (0.99). Through FT-IR and XPS studies, it was determined that ion exchange, surface complexation, and chelation were the primary mechanisms responsible for removing the analytes from water using MPM as sorbent. The presence of the -CS2-Na group in MPM played a crucial role in these removal mechanisms. Additionally, MPM displayed notable antibacterial efficacy against S. aureus and E. coli. Considering its rapid kinetics, wide pH range applicability, impressive sorption capacity, recyclability, and effective antibacterial properties, MPM proves to be a highly suitable adsorbent for removing Hexavalent chromium and Cd(II) from industrial wastewater.
