| description | The presented research applied the modified Halloysite nanoclay to boost the adsorption efficacy of heavy metals from the water. To improve As (III) adsorption effectiveness from water, the study assessed the characteristics of the prepared materials and improved the experimental conditions. The study was optimized the experimental condition with a dosage of 1 g/L, contact time of 90 min, the solution pH of 8, and the initial concentration of 5 ppm of As (III). The optimization was performed in distilled water and later the experiments were conducted in the real polluted water. The modified Halloysite nanoclay’s physical characteristics were investigated using techniques like X-ray diffraction, scanning and transmission electron microscopy, Fourier transform infrared spectroscopy, and surface area analysis. The experimental result shows the adsorption efficiency of 82.4 % of As (III) at the optimized condition during the usage of modified Halloysite nanoclay. To create a suitable mathematical model for a better description of the interactions between pollutants and solid adsorbents, it is helpful to analyze the process kinetically. The removal process of As (III) was studied kinetically and the observation shows the pseudo-second order kinetics. |
