Removal of Arsenic from synthetic-water using Iron Coated Sand Adsorbent and Modified Ceramic Clay House Hold Pitcher

Abstract

This study focuses on the preparation of iron coated sand adsorbent and modified ceramic clay pitchers, that can be used for the removal of As(V) from synthetic water. Iron coated sand adsorbent with particle size 150μm and three forms of iron coated sand ceramic clay pitchers were prepared with differing ratios of ceramic clay and iron coated sand with iron sulfide (FeS) and iron chloride hexahydrate (FeCL3.6H2O). The ratios of ceramic clay and iron coated sand were taken as 75:25, 60:40, and 40:60 appropriately. The performance assessment of ICSA and three forms of pitchers was carried in a batch process. The As(V) adsorption/removal rate of ICSA and ICSA ceramic clay Pitcher were analyzed using atomic adsorption spectroscopy (AAnalyst700, PerkinElmer, USA). The results indicated that the ICSA has removal efficiency up to 94-98%, and ICSA ceramic clay pitcher’s made of river sand coated with iron sulfide and iron chloride hexahydrate along with ceramic clay with the ratio of 60:40 have acceptable As(V) removal efficiency up to 40%. The prepared pitcher was considered acceptable for the As(V) removal purpose. The designed pitchers can be prepared in the local market without any trouble and can be used regularly for As(V) removal purposes.
