description The invention relates to a method for removing iron and aluminum continuously from yttrium-rich feed liquid through N235. The method includes the steps of yttrium-rich feed liquid preparation, N235 extraction agent preparation, entry of feed liquid in an extraction groove, extraction and impurity removal and the like, wherein purified yttrium-rich feed liquid comprises not larger than 50 PPM of Fe2O3 and not larger than 40 PPM of Al2O3. By means of the method, impurities such as the iron and the aluminum in the yttrium-rich feed liquid can be removed efficiently, the processes of extraction for iron and aluminum removal and back extraction for discharging waste water containing the iron and the aluminum are linked up, and the whole production process has consistency and is simple in process, easy and convenient to operate and low in cost.
