Citric acid and copper are often found in the waste streams from semiconductor manufacturing. They are likely to form complexes, which modify copper speciation. This can lead to changes in sorption mechanisms and the sorption capacity. PEI-agarose adsorbents in a packed bed column are capable of removing these anionic complexes, but the competitive binding between these organic ligands and PEI for...
The effects of humic acid (HA) on As(V) removal by zero-valent iron (Fe 0 ) from groundwater, associated with corrosion products analyses, were investigated using batch experiments. It was found that arsenic was rapidly removed from groundwater possibly due to its adsorption and co-precipitation with the corrosion products of Fe 0 . The removal rate of arsenic by Fe 0 was inhibited...
