摘要

本研究报道了采用原位热解和共沉淀法合成纳米结构碳包覆铁氧体钡。通过XRD、TEM和BET分析对所得材料进行了表征，证实了其纳米结构和高比表面积。该吸附剂可有效去除水溶液中的六价铬（Cr(VI)），在最佳条件下去除率高达92%。吸附遵循多层伪二级动力学过程，材料在六个重复使用循环中保持了显著的效率。这些发现突出了碳包覆铁氧体钡作为一种有前途的水净化吸附剂的潜力。

Nanostructured Carbon-Coated Barium Ferrite for Efficient Cr(VI) Adsorption: Synthesis and Performance Evaluation

The study reports the synthesis of nanostructured carbon-coated barium ferrite via a combined in-situ pyrolysis and co-precipitation approach. The resulting material was characterized using XRD, TEM, and BET analysis, confirming its nanostructure and high surface area. The adsorbent demonstrated efficient removal of hexavalent chromium (Cr(VI)) from aqueous solutions, achieving up to 92% removal under optimal conditions. Adsorption followed a multilayer process with pseudo-second-order kinetics, and the material retained significant efficiency over six reuse cycles. These findings highlight the potential of carbon-coated barium ferrite as a promising adsorbent for water purification applications.
