Preparation method of polycrystalline silicon ingot

The invention relates to a preparation method of a polycrystalline silicon ingot. The method comprises the following steps: (1) a binding agent, a dispersing agent, and silicon particles of which the purity is above 99.9 percent and the diameter is between 1 [mu]m and 5,000 [mu]m, are added into deionized water, a pulp is obtained after uniform mixing, and the mass percentage of the silicon particles in the pulp is not less than 50 percent; (2) in a quartz crucible with a silicon nitride coating on the inner surface, the pulp is applied on the surface of the silicon nitride coating through spray coating, roller coating or brush coating, so as to form a pulp layer with a thickness between 1 mm and 10 mm; the crucible with a silicon coating is obtained after drying; (3) the crucible with the silicon coating is sent into a polycrystalline silicon ingot furnace after being loaded with silicon materials, the silicon materials are heated after vacuum pumping, a silicon material melt is cooled ...

Red ginseng extract as well as preparation method and application thereof

The invention discloses a red ginseng extract. The extract is characterized by containing ginsenoside Rg1, ginsenoside Re, ginsenoside Rf, notoginsenoside R2 and ginsenoside Ro. A preparation method of the extract comprises the following steps: cutting red ginseng serving as a medicinal material into pieces, adding water in an amount which is 3-10 times that of the red ginseng, soaking for 0.5-2 hours, heating and performing reflux extraction for 1-2 hours, extracting for 1-3 times, combining extraction solutions, filtering and concentrating; separating and purifying a concentrated solution with a reverse phase silica gel column; eluting with 30-40 percent methanol-water by 4-10L, and discarding; and eluting with 50-70 percent methanol-water by 4-6L, collecting an eluent and concentrating to obtain active ingredients.

Method for rapidly detecting contents of saponin

The invention provides a method for rapidly detecting contents of saponin. The method comprises the following steps: measuring spectrograms of liquids including loading flow-out liquid, rinsing flow-out liquid, eluant and the like in a column chromatography process by using an attenuated total reflection-ultraviolet visible spectrophotometer, establishing a quantitative model of the contents of saponin and the spectrograms by using a chemometrics method, directly scanning an ultraviolet-visible light spectrogram of chromatography flow-out liquids with unknown concentrations while analyzing a to-be-detected sample, inputting data of the light spectrogram into the quantitative model, and calculating the contents of saponin in the chromatography flow-out liquids. The method is simple and rapid and pollution-free; the sample does not need to be diluted or filtered; the method can be used for rapidly detecting contents of saponin in different flow-out liquids in the column chromatography process ...
