반응 단계
A process, as claimed in claim 1, wherein sodium hydrogen sulfate is added to the extractive liquor, to obtain a Ph value of 6-7, and the neutral sodium chromate solution is acidified with sodium hydrogen sulfate again; and further, sucrose or formaldehyde is added, followed by heating to above 100° C., to form chromium sulfate and sodium sulfate, which, after completion of reaction, are cooled to 21°-24 C., and separated, to obtain sodium sulfate decahydrate crystals and chromium sulfate.
