Improved method for precipitation of insoluble salts in divalent ion-form materials |
| abstract |
Selected polyvalent anions or cations are removed from a liquid sample stream as a pretreatment for the analysis of the liquid sample stream. A stream containing anions of interest, precipitable anions (e.g. sulfate ions) to be removed and an added displacing salt having a polyvalent cation flow through a cation exchange resin bed having precipitable exchangeable polyvalent ions (e.g. barium ions). The polyvalent cation (e.g. calcium) of the displacing salt exchanges with the cation of the resin, which reacts with the precipitable anion to form a precipitate which is retained in the bed. The anions of interest are subsequently separated and analyzed. The invention is also applicable to the removal of precipitable cations (e.g. barium ions) by reversing the roles of the anions and cations. |
