The presence of regulated inorganic contaminants in water such as AsO₄³⁻ and PO₄³⁻ anions, is becoming a relevant environmental research topic. The harm that these anions cause to human health and the ecosystem have been reported in several works. The adsorption processes using low-cost materials, such as zeolites, have proven to be an option to removal hazardous contaminants from water. The coal fly ash, a waste from thermoelectrical plants, offers a raw pollutant material to synthesis an effective adsorbent (Zeolite W). In this research was studied the removal of arsenic and phosphates anions from water, applying a functionalized by iron and zirconium Zeolite W, which was modified using a fast and efficient process through microwave-assisted method (1 min at 150°C). The obtained Zeolite W did not show significant changes in its structure and morphology. The maximum adsorption capacity (Qm expressed in mg g⁻¹) was found to be 42.31 (Iron-zirconium-zeolite) and 27.82 (Iron-zeolite) for AsO₄³⁻, while it reached 50.89 for PO₄³⁻ using Zirconium-zeolite. Results showed that functionalized zeolites are efficient adsorbents for hazardous anionic species; therefore, it could be useful for aqueous effluents remediation.

水中存在受管制的无机污染物，例如AsO ₄ ^3-和PO ₄ ^3-阴离子，正成为相关的环境研究主题。这些阴离子对人体健康和生态系统的危害已在几篇著作中进行了报道。使用低成本材料（例如沸石）的吸附过程已被证明是去除水中有害污染物的一种选择。粉煤灰是热电厂的废料，它提供了一种原始污染物来合成有效的吸附剂（沸石W）。在这项研究中，我们研究了使用铁和锆沸石W进行官能化处理后从水中去除砷和磷酸盐阴离子的方法，该方法通过微波辅助方法（在150°C下1分钟）使用快速高效的方法进行了改性。所获得的沸石W在其结构和形态上没有显示出明显的变化。最大吸附量（Qm，以mg·g表示AsO ₄ ^3-的-1）为42.31（铁-锆-沸石）和27.82（铁的沸石），而使用锆-沸石的PO ₄ ^3-则为50.89 。结果表明，功能化沸石是有害阴离子物质的有效吸附剂。因此，对废水的修复可能是有用的。
