Electrocoagulation (EC) using iron electrodes is a promising arsenic removal strategy for Bangladesh groundwater drinking supplies. EC is based on the rapid in situ dissolution of a sacrificial Fe(0) anode to generate iron precipitates with a high arsenic sorption affinity. We used X-ray absorption ...

Bangladesh and neighbouring areas face health threats from drinking arsenic-contaminated groundwater.The challenge is to develop arsenic remediation that is (1) affordable to most of the local population, (2) robust and easy to maintain long term, (3) technically effective for removing arsenic down ...

Bangladesh and neighboring areas face large health threats from drinking arseniccontaminated ground water. Arsenic levels in Bangladesh ground water are typically several hundred ∝g/L (compared to WHO recommendation of 10 ∝g/L for the MCL). About 50 million people drink such water, with hundreds of ...

The formation of Fe(III) (oxyhydr)oxide precipitates from Fe(II) oxidation and/or Fe(III) hydrolysis is a key process that often governs the fate and bioavailability of contaminants and nutrients in natural and engineered systems. Electrocoagulation (EC) using Fe(0) electrodes is a low-cost water tr...
