The present research focuses on the adsorption efficiency of nano-magnetite loaded 2-mercapto- benzoxazole as an adsorbent (Fe₃O₄@SiO₂@CPTMS@MBOL) for Pb⁺², Ni⁺² and Cd⁺² removal from the contaminated water by the technique of adsorption. The influence of pH, contact time, adsorbent dosage and temperature in 50 ppm concentration of each ion solutions on the sensitivity of the removal procedure was examined. By ICP test the adsorption data were fixed to linearize the adsorption isotherms of the Langmuir and Freundlich equations. This efficient adsorbent showed significant results for metal ion removal from water by formation of complex with adsorbent. From the Langmuir isotherm, the maximum adsorption capacities of nano magnetic adsorbent towards Pb²⁺, Ni²⁺ and Cd²⁺ ions were 238.4, 203.2 and 22.37 mgg⁻¹.

目前的研究重点是纳米磁铁矿负载的 2-巯基苯并恶唑作为吸附剂（Fe ₃ O ₄ @SiO ₂ @CPTMS@MBOL）对 Pb ⁺²、Ni ⁺²和 Cd ⁺²的吸附效率用吸附技术从污染水中去除。检查了每种离子溶液的 50 ppm 浓度下的 pH 值、接触时间、吸附剂剂量和温度对去除程序敏感性的影响。通过ICP测试，吸附数据被固定以使Langmuir和Freundlich方程的吸附等温线线性化。这种高效的吸附剂通过与吸附剂形成络合物而从水中去除金属离子显示出显着的效果。根据朗缪尔等温线，纳米磁性吸附剂对Pb ²⁺、Ni ²⁺和Cd ²⁺离子的最大吸附容量分别为238.4、203.2和22.37 mgg ^-1。
