REMOVAL OF CHLORIDE ION FROM WATER BY USING ADSORBENTS

摘要

Chloride is commonly present in water as Sodium Chloride. Concentration of Chloride above 250 mg/l imparts a salty taste to water. Excess Chloride concentration in water is responsible for the cardiovascular diseases & corrosion of RCC structures. In order to avoid these problems, removal of excess Chloride from water is desired. There are various methods available for the removal of chloride from water, such as reverse osmosis (R.O.), and distillation. These methods are costly and have some limitations. Therefore, the adsorption process which is alternatives to these methods can be used effectively. In our study, we have used different adsorbents i.e. Neem leaf powder, Coconut shell powder and Charcoal powder and examine their efficiency of Chloride removal at neutral pH and at room temperature. Keeping the pH Controlled at 7 by using 0.1N HCl & 0.02N NaOH as acid/basic solution, the Chloride removal efficiency of each adsorbent will depend upon its doses and contact time for mixing.
