Abstract

This study investigates the effectiveness of a Schiff base derived from thio-carbohydrazide and salicylaldehyde as an adsorbent for Cr(VI) removal from wastewater. The Schiff base demonstrated excellent adsorption capacity and reusability, with high removal efficiency and rapid adsorption kinetics. The results were supported by theoretical density functional theory simulations, which revealed the enhanced dynamic nature of the Schiff base system for heavy metal adsorption. These findings highlight the potential of Schiff base complexes as sustainable and efficient adsorbents for industrial wastewater treatment.

摘要

本研究考察了一种由硫代碳酰肼和水杨醛衍生的席夫碱作为从废水中去除Cr(VI)的吸附剂的有效性。该席夫碱表现出优异的吸附容量和可重复使用性，具有高去除效率和快速的吸附动力学。理论密度泛函理论模拟结果支持了这些结果，该模拟揭示了席夫碱体系对重金属吸附的增强动态特性。这些发现突出了席夫碱配合物作为工业废水处理中可持续且高效吸附剂的潜力。
