摘要：A simple,low cost arsenic removal system was developed to treat arsenic contaminated ground water containing 425 ± 4.2 µg/L arsenic. The system decontaminates arsenic from water by sorption through fine particles of waste materials (Coconut husk’s ash,Refused brick dust,Stone dust and Waste newspaper) of multilayer. The treatment efficiency of the process was investigated under various operating conditions that might affect the sorption/ desorption of arsenic. Sorption column method shows the optimum removal of As(III) under the following conditions: initial As concentration (100 µg/L),sorbent amount (4.0 g for brick dust,3.0 g for stone dust,3.0 g for Coconut husk’s ash and 0.3 g for waste newspaper),particle size (..
