The Comprehensive Utilization of Waste Water Derived from the Glyphosate Production

The glyphosate solution, sodium chloride and phosphate solid are separated concurrently by using different mixed solvent extraction processing from glyphosate production wastewater. Among them, ethanol-acetone is the best solvent extraction agent. In glyphosate solution after treatment, glyphosate content is 6.14 %, meanwhile, the content of sodium chloride and phosphate is rather low. So, it can be used as glyphosate agent production. The content of sodium chloride is up to 98 % after recrystallization, which can be as the raw material of chlor-alkai production. When the mother liquor of recrystallization combined with the original wastewater, the glyphosate can be close to the maximum recovery.
