草甘膦母液的沉淀处理研究
Precipitation Treatment of Glyphosate Mother Liquor
摘要
Abstract
[ Objective] The aim was to study a removal method of HP032 - from glyphosate mother liquor. [ Method] Effects of precipitant quantity and type,pH and standing time on the removal rate of HPO32- from glyphosate mother liquor were studied by chemical precipitation method.[Result] When the initial pH was 9,the following pretreatment procedure resulted in the removal rate of more than 60% of the HP03 2- from glyphosate mother liquor;the addition of 0.24 mol/L A1C13 · 6H2O,stirring at 300 r/min for30 s and 100 r/min for 2.5 min,followed by standing for 30 min. [ Conclusion] The research result provides theoretical basis for the industrial popularization and application of membrane technology in resourceful treatment of glyphosate mother liquor.关键词
