With industrialization, wastewater treatment technologies have drawn huge attention and among different approaches the adsorption process is very attractive because of its simple design and low operational cost. In this paper, CoCu-layered double hydroxide (LDH) was prepared having huge surface area with a large pore diameter, which is significant for obtaining excellent adsorption properties for methyl orange (MO). After detailed adsorption kinetics analysis, the results followed pseudo second order (PSO) kinetic model having good correlation coefficient (R²) values. However, adsorption isotherms data matched well with the Freundlich isotherm kinetics model. Furthermore, CoCu-LDH exhibits significant adsorption capacity even in the fifth cycle of MO adsorption, indicating that the CoCu-LDH is competitive and cost-effective adsorbent for anionic dyes from industrial wastewater.

随着工业化，废水处理技术引起了极大的关注，并且在不同的方法中，由于其简单的设计和较低的运行成本，吸附过程非常有吸引力。本文制备了具有大表面积和大孔径的CoCu层状双氢氧化物（LDH），这对于获得优异的甲基橙（MO）吸附性能具有重要意义。经过详细的吸附动力学分析，结果遵循具有良好相关系数（R ²）的拟二阶（PSO）动力学模型。价值观。但是，吸附等温线数据与Freundlich等温线动力学模型非常吻合。此外，即使在MO吸附的第五个循环中，CoCu-LDH仍显示出显着的吸附能力，这表明CoCu-LDH对工业废水中的阴离子染料具有竞争性和成本效益。
