Abstract Presence of nitrate and phosphate ions is difficult to remove from the lakes, as they are highly soluble in water. A way of chemical method adopted to remove these ions from the drinking water using the simple method use of naturally abundant chitosan with charcoal. Adsorption of nitrate and phosphate anions from aqueous solution (water/waste water) on both the chitosan and activated charcoal was investigated. In batch mode adsorption study leads to developing efficient low-cost removal method is important to protect the aquatic environment from the high concentration of nitrate and phosphate anions intake as well as adverse effects on human health. The modified chitosan microspheres had a laudable performance for nitrate and phosphate adsorption Use of this material as an adsorbent is a cheaper and biocompatible method. A systematic study of the adsorption of nitrate and phosphate anions on chitosan and activated charcoal was performed by varying the pH, the initial concentration, contact time, and adsorbent dosage. The results demonstrate that the adsorption process was followed adsorption kinetics of both first and second order kinetics when we use of the chitosan and activated charcoal and chitosan is promising for treating water that is contaminated with nitrate and phosphate anions.

通过低成本壳聚糖和活性炭轻松去除水中的硝酸根和磷酸根阴离子

摘要 硝酸根和磷酸根离子的存在很难从湖泊中去除，因为它们极易溶于水。一种通过使用天然丰富的壳聚糖和木炭的简单方法从饮用水中去除这些离子的化学方法。研究了从水溶液（水/废水）中的硝酸根和磷酸根阴离子在壳聚糖和活性炭上的吸附。批量模式吸附研究导致开发有效的低成本去除方法对于保护水生环境免受高浓度硝酸盐和磷酸盐阴离子的摄入以及对人类健康的不利影响很重要。改性壳聚糖微球对硝酸盐和磷酸盐的吸附具有值得称赞的性能 使用这种材料作为吸附剂是一种更便宜且具有生物相容性的方法。通过改变 pH、初始浓度、接触时间和吸附剂剂量，对硝酸根和磷酸根阴离子在壳聚糖和活性炭上的吸附进行了系统研究。结果表明，当我们使用壳聚糖和活性炭时，吸附过程遵循一级和二级动力学吸附动力学，壳聚糖有望用于处理被硝酸根和磷酸根阴离子污染的水。
