  • Optimized time of sequential extraction arsenic in sediment, experiments performed in closed systems with five extractants. - Carried out experiment at different time of optimal process : 0.167h; 0.33h; 0.66h; 1h; 2h; 3h; 6h; 12h;18h;24h. Carried out at 6h for extraction and application of extraction with five sediment samples.- Application of extraction process of sediments to find out the relationship between arsenic in sediment and groundwater and the role of releasing arsenic from sediment into groundwater. - Analysis of 19 samples of groundwater and extracted with 5 samples of sediment. Results of extraction: 0.1% As bound with Non-specifically.25% As bound with solubility ...
