Abstract

How to prepare adsorbents using economical, environmentally friendly and simple methods has become the focus of research. In this paper, silk cotton (SC) was used as a biomass template impregnated with copper nitrate solution and then calcined to prepare CuO-based adsorbent. Carbon-doped CuO (C/CuO-400) adsorbent was obtained under 400 °C air calcination calcination. It completely replicates the morphology of kapok and consists of uniformly smaller nanoparticles. The effects of different calcination temperatures, adsorption temperatures, adsorption times, adsorbent dosages and different concentrations on the adsorption of lead ions were investigated. The results showed that C/CuO-400 had a good adsorption effect on Pb²⁺, which was suitable for Pseudo second-order and Langmuir, and the maximum adsorption amount of Pb²⁺ was 588.24 mg/g with good Reusability. This environmentally friendly, economical and simple to operate biomass template prepared adsorbent of single tube C/CuO has good adsorption effect on lead ions, which is very meaningful and easy to promote the preparation of adsorbent.

碳掺杂 CuO 纳米粒子构建的单管吸附剂在近室温条件下高效吸附 Pb2+

如何利用经济、环保、简单的方法制备吸附剂已成为研究的重点。本文以丝棉（SC）为生物质模板，浸渍硝酸铜溶液，然后煅烧制备 CuO 基吸附剂。掺碳 CuO（C/CuO-400）吸附剂是在 400 °C 空气煅烧下获得的。它完全复制了木棉花的形态，由均匀较小的纳米颗粒组成。研究了不同煅烧温度、吸附温度、吸附时间、吸附剂用量和不同浓度对铅离子吸附的影响。结果表明，C/CuO-400 对 Pb2+ 具有良好的吸附效果，适合伪二阶和 Langmuir 吸附，对 Pb2+ 的最大吸附量为 588.24 mg/g，具有良好的重复利用性。这种环保、经济、操作简单的生物质模板制备的单管C/CuO吸附剂对铅离子具有良好的吸附效果，具有很好的推广意义。
