| Abstract: | Having analysed the pregnant liquor of barium hydroxide produced in the barium chloride method,the author puts forward the technological chain to extract the barium ion and sodium chloride being about 3% and 25% of the pregnant liquor. So.the factory which produces 3000 tons barium hydroxide annually,can re- trieves 1400 tons sodium chloride and 130 tons barium carbonate meeting the national standard. |
