Arsenic is a semi-metal element in the periodic table. It is odorless and tasteless. It can enter drinking water supplies from natural deposits in the earth or from agricultural and industrial practices.

Ion exchange (IX) is a physical-chemical process in which ions are swapped between a solution phase and solid resin phase. Ion exchange arsenic removal is accomplished by continuously passing water under pressure through one or more columns packed with strong-base anion exchange resin.

The exchange affinity of various ions is a function of their net surface charge. Therefore, the efficiency of the anion exchange (IX) process for As(V) removal depends strongly on the concentration of other anions, most notably sulfate and nitrates. These sulfate and nitrates and other anions compete for sites on the exchange resin according to the following selectivity sequence.

SO4-2 > HAsO4-2 > NO-3 , CO3-2 > NO-2 > Cl-

Lanlang ® TA306D is macroporous arsenic selective anion exchange resin, it's functional group is FeO(OH). The arsenic is captured by ion exchange firstly and then adsorbed by the iron oxide dispersed throughout the polymers. TA306D has fast kinetics to remove arsenic and can reduce the arsenic content less than 10ppb.
