Abstract In crystal preparation, ethanol is frequently employed to remove the moisture on the crystal surfaces. However, this process could severely oxidize the products due to the dissolved oxygen in ethanol. Herein, by taking the preparation of ammonium ferrous sulfate crystals as an example, we proposed and demonstrated that the deoxidized ethanol could largely enhance the quality of the easy-oxidized crystals.
