The purpose of this study was to develop a MoS₂-impregnated biochar (MoS₂@BC) via hydrothermal reaction for adsorption of cadmium (Cd) from an aqueous solution. The prepared adsorbents were characterized, and their abilities to remove Cd(II) were evaluated. The Langmuir and pseudo-second-order models better described the removal of Cd(II) by MoS₂@BC. The prepared MoS₂@BC exhibited excellent monolayer adsorption capacity. The S-containing functional groups on MoS₂@BC enhanced the adsorption of Cd(II). Multiple Cd(II) sorption mechanisms were identified; including Cd(II)-π interactions, ion exchange, electrostatic interaction, and complexation. The dominant mechanism involved Cd-O (38.3%) bonds and Cd-S complexation (61.7%) on MoS₂@BC. The as-prepared MoS₂@BC is both economical and efficient, making it an excellent material for environmental Cd(II) remediation.

这项研究的目的是通过水热反应开发一种MoS ₂浸渍生物炭（MoS ₂ @BC），用于从水溶液中吸附镉（Cd）。对制备的吸附剂进行表征，并评估其去除Cd（II）的能力。Langmuir模型和伪二阶模型更好地描述了MoS ₂ @BC对Cd（II）的去除。制备的MoS ₂ @BC表现出优异的单层吸附能力。MoS ₂上的含S官能团@BC增强了Cd（II）的吸附。确定了多种Cd（II）吸附机理；包括Cd（II）-π相互作用，离子交换，静电相互作用和络合。占主导地位的机制涉及MoS ₂ @BC上的Cd-O（38.3％）键和Cd-S络合（61.7％）。所制备的MoS ₂ @BC既经济又高效，使其成为用于环境Cd（II）修复的极佳材料。
