1.将样品按1：5的比例溶于纯水中。
2.加热溶解，溶解温度控制小于80度。
3.待完全溶解后，加入溶液总量0.2-0.4％的活性炭，搅拌30分钟，过滤，虑液无色透明。
4.将滤液于60-70度条件下减压浓缩，浓缩至总体积减少至三分之一；
5.冷却至常温结晶。
6.离心脱母液，至离心机排水口无出水，加入酒精洗2次。
7.清洗后的晶体送至干燥机于65度条件下真空干燥2小时，得成品。
8.母液回收浓缩后再重新结晶。

1. The samples were dissolved in water according to the ratio of 1:5. 2. Heating dissolution and the dissolution temperature less than 80 degrees. 3. When completely dissolved ,adding activated carbon 0.2-0.4% of the total solution, stirring for 30 minutes, filtered, The transparent colorless liquid consideration. 4. Filtrate under vacuum conditions will be concentrated in the 60-70 degrees, to reduce the total volume of concentrate to third; 5. Cooling under nature temperature till crystallized . 6. Centrifugal from mother liquor, no water outfall to centrifuges, adding alcohol washed 2 times. 7. Washed crystal sent to the dry cleaning machine at 65 degrees for 2 hours under vacuum drying, products finished. 8. Then re-concentrated waste liquid crystal.
