ADSORPTION OF CHLORIDE ION FROM POLLUTED WATER USING POMEGRANATE PEELS POWDER AND TEA LEAVES

Abstract

The aim of this research paper is to minimize chloride ion concentration in water using natural materials such as pomegranate peels powder and tea leaves as adsorbent materials. The water samples that tested in this study were collected from one of Baghdad’s public swimming pools. Influence of contact time and temperature on removal efficiency was investigated. The results showed that after 60 minutes of contact time the chloride ion’s concentration was decreased from (873.3 mg/L) as initial concentration to (213 mg/L) and (234.3 mg/L) when using pomegranate peels powder or tea leaves respectively. In addition, results showed that increasing solution temperature would improve adsorption capability of adsorbent material that used in this study, increasing solution temperature to (100 oC) reduces chloride ion concentration from (873.3 mg/L) as initial concentration to (206 mg/L) and (220.1 mg/L) using pomegranate peels powder or tea leaves respectively. Comparing the effect of contact time and temperature on adsorption process showed that temperature had rapid effect for both adsorbent tested material, while pomegranate peels powder was more effective than tea leaves in chloride ion’s concentration reduction.
