Nowadays, Cr-loaded wastewater released from industrial activities pose an increasing risk to human health and the environment. Adsorption processes have been widely used for the removal of chromium from the waste stream. In this regard, natural adsorbents are the most preferable and cost-effective methods. In this study, the efficiency of Odaracha adsorbent as a novel green technology in the removal of chromium from synthetic wastewater is analyzed. Batch adsorption experiments were conducted to evaluate the effect of contact time, pH, adsorbent dose, and initial concentration of adsorbate on Cr removal. The surface morphology of Odaracha adsorbent was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray powder diffraction. Experimental results showed that Odaracha adsorbent could perform effectively in a wide range of experimental conditions. However, in optimum experimental conditions, such as 180-min contact time, pH 3, and 15 g/L of adsorbent dose Odaracha adsorbent removes 94.68% of Cr from an aqueous solution having 110 mg/L of Cr concentration.

如今，工业活动释放的含铬废水对人类健康和环境构成了越来越大的风险。吸附工艺已广泛用于从废物流中去除铬。在这方面，天然吸附剂是最优选和最具成本效益的方法。在这项研究中，分析了Odaracha吸附剂作为一种新型绿色技术从合成废水中去除铬的效率。进行了批量吸附实验，以评估接触时间，pH，吸附剂剂量和吸附物初始浓度对Cr去除的影响。Odaracha吸附剂的表面形貌通过扫描电子显微镜，傅立叶变换红外光谱和X射线粉末衍射进行表征。实验结果表明，Odaracha吸附剂可以在各种实验条件下有效发挥作用。但是，在最佳的实验条件下，例如180分钟的接触时间，pH 3和15 g / L的吸附剂量，Odaracha吸附剂从Cr浓度为110 mg / L的水溶液中去除了94.68％的Cr。
