摘要
采用0.2μm的Al2O3膜,精滤工业碳酸钠溶液、含草酸钴水溶液和硫酸镍溶液等,研究获得这些溶液的技术参数,为陶瓷膜的工业化应用提供基础数据.实验结果表明,经陶瓷膜精滤后的溶液清晰、透明,有价金属杂质离子含量和含油量降低,精滤后溶液的物理和化学指标可达到工业生产的标准.采用陶瓷膜精滤工业碳酸钠溶液、含草酸钴水溶液、硫酸镍溶液等能够保持较高的膜通量,而且受污染的膜经过清洗和再生,通量可以恢复,能满足工业连续生产的要求.
The filtration of industrial sodium carbonate solution,oxalate cobalt solution, Rare-earth solution and nickel sulphate carbonate solution was carried out using inorganic Ceramic Membrane. The experimen tal results show that the permeate was clear, and the content of metal ion was lower. The membrane flux was larger and stable. Ceramic membrane flux can be recovered by chemical clean. The result shows that the ceramic membrane used to treatment the industrial Sodium carbonate solution,oxalate cobalt solution and nickel sulphate carbonate solution was technology reasonable, and can be used in the industry application.
