PROCESS FOR THE PREPARATION AND SEPARATION OF VANADIUM SALTS FROM WAESSEN SOLUTIONS |
| abstract |
The invention relates to a process for the separation of vanadium from aqueous Vanadiumsalzloesungen. The developed process can be used in oil-based power generation plants, the chemical industry and the steel industry. The accumulating wastewater is freed of sediment, according to the vanadium content with 1 m Fe-II-SO deep 4-solution provided and adjusted with lye according to the invention a pH 9.5. The filtrate of this solution contains 3 - 5 mg V deep 2 O deep 5 / l. If necessary, the solution thus obtained can be subjected to reverse osmosis at about 3 MPa. This permeate is characterized by a filtrate concentration of 1 - 4 mg V deep 2 O deep 5 / l. |
