摘要
We examined the desalination treatment of seawater using AgNO3 and Pb(NO3)2 for the removal of anions, such as Cl-, Br-, and SO42-. AgNO3 could remove Br- and Cl- from seawater, while Pb(NO3)2 could remove SO42-, Br- and Cl-. The pH of solution treated with AgNO3 was constant at pH 8.1, but the pH of the solution treated with Pb (NO3)2 decreased to acidic. The reactions of AgNO3 and Pb(NO3)2 with anions in seawater were rapid. Regardless of temperature of seawater, the time for anion removal by AgNO3 was almost same, while that by Pb(NO3)2 delayed with decreasing temperature of seawater.
