提纯钪的离子交换法美国通用电话电子公司实验室研究的离子交换法是将含钪原料浴解于酸溶液后，再将ｐＨ２０５～３．５的这种溶液用具有亚氨二醋酸功能作用的氢回型螯树脂处理。接着调整泥浆至ｐＨ１．９～１２５，脱水，用稀的无机酸漂洗泥浆，再用二甘油酸脱除吸附于螯...
Purification of scandium ion exchange method US General Telephone Laboratory research ion exchange method is to scandium raw materials containing bath solution in acid, and then this solution pH205 ~ 3.5 with iminodiacetic acid function of the role of Hydrocrack chelating resin treatment. Then adjust the slurry to pH1.9 ~ 125, dehydration, rinse the slurry with dilute mineral acid, and then remove the adsorption of diglycerol adsorbed on the chelate ...
