目的:降低草甘膦原药中的钠离子含量,提高产品质量。方法:在单因素试验的基础上,通过正交试验确定生产过程工艺指标和洗涤方式的调整方法,并在生产中得以验证。结果:草甘膦中钠离子指标达500ppm以下的产品合格率达到90%以上。结论:控制草甘膦原药中的钠离子含量在500ppm以下,操作简单可行,可以大规模推广。
Objective: To reduce the content of sodium ion in glyphosate original drug and improve product quality. Methods: On the basis of single factor test, the orthogonal test was used to determine the process parameters of the production process and the adjustment method of the washing method, which was verified in production. Results: The qualified rate of products with glyphosate index of 500ppm or less reached more than 90%. Conclusion: The control of glyphosate in the sodium ion content of less than 500ppm, the operation is simple and feasible, can be large-scale promotion.
