1) dissolving Aloe stone in acid water, and filtering to obtain barbaloin water solution; 2) oxidizing the barbaloin water solution to obtain aloe-emodin crude product and acidic wastewater;

3) evaporating the acid wastewater, circularly using the evaporated dilute acid in the step 1), cooling, crystallizing and filtering mother liquor to obtain organic FeCl₂ And dilute acid;

4) adding dilute acid to the mixture, and filtering to obtain insoluble black solid and FeCl₂ Filtering the solution;

5) to FeCl₂ Introducing oxygen into the filtrate to generate Cl3Fe, and recycling the Cl3Fe for the step2); washing the insoluble black solid with water to neutrality, and purifying with the aloe-emodin crude product obtained in step 2) to obtain Aloe Emodin Powder.
