Study on Conditions of Y(OH) 3 Complete Precipitation in NH 3 CO 2 System

Wang Weimin and Yuan Zhendong (Department of Chemistry, Anyang Normal College, Anyang 455000, China)  
Y 3+ in NH 3·H 2O solution can precipitate in the form of Y(OH) 3, the molar ratio of HCO 3 - to CO 3 2- in the system changes with the final pH. Y(OH) 3 is soluble in water and changes into [Y(HCO 3) n ] 3- n or [Y(CO 3) n ] 3-2 n . The influences of the concentration of HCO 3 - and CO 3 3- on the precipitation rate of Y(OH) 3 were discussed, when CO 2 is flowed into the solution in which the concentration of NH 3·H 2O was different and the final pH was 8.00 or 10.00. The conditions of Y(OH) 3 complete precipitation were obtained.
