硫化钡及氨水净化农用氯化铵的研究

Study on Purifying Agricultural Ammoniacal Chloride with Barium Sulphide and Ammoniacal Liquor

比较了硫化钡及氨水对农用氯化铵的净化效果,结果表明,硫化钡的净化效果较好,制得的工业氯化铵,白色度较高,且生产成本较低。

The effect of puring agricultural ammoniacal chloride with barium sulphide and ammoninacal liquor was compared. The results showed that it can be obtained better purifying effect and lower cost of production and higher white industrial ammoniacal chloride by using barium sulphide.
