Novel KMnO4-modified iron oxide for effective

2011-12-30  Among these, adsorption is considered to be easy and cost-efficient. Much research on appropriate adsorbents for removing arsenic has recently been conducted. Iron oxides are the most popular adsorbents owing to their high affinity for inorganic arsenic species,,,, . However, As (III) adsorption is generally less effective than the As (V) adsorption.

2021-6-1  In Fig. 6, Fig. 7, the effect of the advection velocity and resin dose for arsenic removal was confirmed in the advection velocity range of 1.1 × 10 −4 to 2.2 × 10 −4 m/s, which is equivalent to a space velocity range of 20 to 40 h −1. In both figures, the faster the advection velocity, the earlier the breakthrough for As(V) removal.
