In this work, Keggin type phosphomolybdate inorganic‐organic hybrid material coordinated to with iron was synthesized by hydrothermal process followed by precipitation with organic cation. The prepared hybrid was fully characterized using conventional spectroscopic techniques. The adsorption efficiencies of the hybrid were evaluated for the removal of both anionic and cationic dyes from aqueous solutions. From the studies, it was concluded that hybrid has high adsorption as well as high selectivity for anionic dyes than cationic dyes. The results from the adsorption experiments revealed that the hybrid have specific methyl orange dye removal efficiency ≥96 % for 20 mgL⁻¹ concentration. The reaction kinetics and adsorption isotherm also discussed.

表面活性剂包封的铁（III）配位的磷钼酸盐杂化物：选择性去除阴离子染料的新型吸附剂。

在这项工作中，通过水热过程，然后用有机阳离子沉淀，合成了与铁配位的Keggin型磷钼酸无机有机杂化材料。使用常规光谱技术对制备的杂种进行了充分表征。评价了杂化物的吸附效率，以从水溶液中去除阴离子和阳离子染料。从研究中可以得出结论，与阳离子染料相比，杂化物对阴离子染料具有高吸附性和高选择性。吸附实验的结果表明，该杂化物在20 mgL ^-1浓度下具有特定的甲基橙染料去除效率≥96％。还讨论了反应动力学和吸附等温线。
