  • Behaviors of arsenic leaching factors imaging the Bangladesh aquifers

抄録

The influences of various chemicals causing anaerobic arsenic leaching from sediment towards groundwater in the alluvial aquifers in Bangladesh were investigated. Consequently, significant influence on arsenic leaching was observed by using phosphoric acid as a leaching agent. Leaching was further promoted when organic phosphate particularly triphenylphosphine, concentration 630 times against control, was utilized. Conversely, remarkable arsenic leaching was also noticed in an alkaline condition by using ammonia. Besides, functions of microorganisms were also examined. Finally, estimation of sorption reaction coefficients was performed to be used with the fundamental equations illustrating arsenic transport in the reducing aquifers.
