摘要

凹凸棒土因其优异的离子交换能力和络合特性，广泛应用于重金属吸附材料的研究与开发。本研究通过碱热改性技术，成功制备了一种重金属高效吸附材料（500-ATP-OH），该材料在吸附Cd（II）和Pb（II）方面性能优异。改性后的凹凸棒土通过离子交换作用，实现了晶体结构的优化，增加了材料的比表面积和孔容。研究结果表明，碱热改性处理后的凹凸棒土材料（500-ATP-OH）对Cd（II）的吸附去除率高达99%，吸附容量为123 mg/g；对Pb（II）的吸附去除率更是达到了100%，吸附容量高达331 mg/g。可见，500-ATP-OH作为一种低成本、环境友好型材料，在处理重金属污染水体方面有较大应用潜力。

Abstract

Attapulgite has been widely studied and used for heavy metal adsorption materials due to its excellent ion exchange ability and complexation properties. In this study

500-ATP-OH as highly efficient adsorbent was successfully prepared by alkaline thermal modification technology. The material has excellent performance in adsorbing Cd(II) and Pb(II). The modified attapulgite realizes the optimization of crystal structure through ion exchange

and increases the specific surface area and pore volume of the material. The results showed that the adsorption and removal rate of 500-ATP-OH for Cd(II) was as high as 99%

and the adsorption capacity was 123 mg/g. The adsorption removal rate of Pb(II) reached 100%

and the adsorption capacity was as high as 331 mg/g. The results revealed that 500-ATP-OH

as a low-cost and environmentally friendly material

had great application potential in treating water polluted by heavy metals.
