Comparison of inorganic and composite ferric oxide sorbents for arsenic removal.
Three different sorbents based on hydrated ferric oxide (GEH, ArsenX(np) and Lewatit FO 36) were compared from the viewpoints of their column operation. Particle size distribution, pressure drop across the column and ferric oxide content were measured. Sorption capacities under the presence of accompanying ions were measured in batch wise and column experiments.
