摘要

从污水中去除罗丹明6G和酸性橙10染料至关重要，因为它们会诱发癌症并刺激肺部、皮肤、粘膜和眼睛。因此，在目前的工作中，Pechini溶胶-凝胶法用于在600和800°C下容易合成ZrO2/CdMn2O4/CdO作为新型纳米复合材料。合成的纳米复合材料被用作新型吸附剂，用于从水介质中有效去除罗丹明6G和酸性橙10染料。在600和800°C下合成的纳米复合材料分别缩写为EK600和EK800。通过EDS、XRD、N2吸附/脱附分析仪和FE-SEM对合成的纳米复合材料进行了表征。XRD图谱显示，EK600和EK800纳米复合材料的平均晶粒尺寸分别为68.25和85.32nm。此外，FE-SEM的图像显示，EK600纳米复合材料的表面由球形、多面体和棒状组成，平均晶粒尺寸为99.36nm。此外，EK800纳米复合材料的表面由多面体和球形组成，平均晶粒尺寸为143.23nm。此外，EK600和EK800纳米复合材料的BET表面积分别为46.33和38.49m2/g。获得罗丹明6G和酸性橙10染料最高去除率的最佳条件是pH=8，接触时间=24min，温度=298kelvin。EK600和EK800吸附剂对罗丹明6G染料的最大去除能力分别为311.53和250.63mg/g。此外，EK600和EK800吸附剂对酸性橙10染料的最大去除能力分别为335.57和270.27mg/g。使用EK600和EK800吸附剂对罗丹明6G和酸性橙10染料的去除是自发的、放热的，遵循Langmuir吸附等温线，并且很好地符合伪一级动力学模型。

Efficient Disposal of Rhodamine 6G and Acid Orange 10 Dyes from Aqueous Media Using ZrO2/CdMn2O4/CdO as Novel and Facilely Synthesized Nanocomposites

It is essential to remove rhodamine 6G and acid orange 10 dyes from contaminated water because they can induce cancer and irritate the lungs, skin, mucous, membranes, and eyes. Hence, in the current work, the Pechini sol–gel method was used for the facile synthesis of ZrO2/CdMn2O4/CdO as novel nanocomposites at 600 and 800 °C. The synthesized nanocomposites were used as novel adsorbents for the efficient removal of rhodamine 6G and acid orange 10 dyes from aqueous media. The nanocomposites, which were synthesized at 600 and 800 °C, were abbreviated as EK600 and EK800, respectively. The synthesized nanocomposites were characterized by EDS, XRD, N2 adsorption/desorption analyzer, and FE-SEM. The patterns of XRD showed that the average crystal size of the EK600 and EK800 nanocomposites is 68.25 and 85.32 nm, respectively. Additionally, the images of FE-SEM showed that the surface of the EK600 nanocomposite consists of spherical, polyhedral, and rod shapes with an average grain size of 99.36 nm. Additionally, the surface of the EK800 nanocomposite consists of polyhedral and spherical shapes with an average grain size of 143.23 nm. In addition, the BET surface area of the EK600 and EK800 nanocomposites is 46.33 and 38.49 m2/g, respectively. The optimal conditions to achieve the highest removal of rhodamine 6G and acid orange 10 dyes are pH = 8, contact time = 24 min, and temperature = 298 kelvin. The greatest removal capacity of the EK600 and EK800 adsorbents towards rhodamine 6G dye is 311.53 and 250.63 mg/g, respectively. Additionally, the greatest removal capacity of the EK600 and EK800 adsorbents towards acid orange 10 dye is 335.57 and 270.27 mg/g, respectively. The removal of rhodamine 6G and acid orange 10 dyes using the EK600 and EK800 adsorbents is spontaneous, exothermic, follows the Langmuir adsorption isotherm, and fits well with the pseudo-first-order kinetic model.
