摘  要:
采用高效液相色谱法,以磷酸二氢钾缓冲溶液作为流动相,Hypersil SAX色谱柱,流速0.8mL/min,紫外检测器波长195nm下同柱分析草甘膦和双甘膦的含量。结果表明草甘膦和双甘膦的线性相关系数为0.9999和0.9984,标准偏差为0.0899和0.7701,变异系数为0.1620%和0.9660%。

摘  要:
The quantitative analysis of glyphosate and N-(phosphonomethyl)iminodiacetic acid was conducted using HPLC with potassium dihydrogen phosphate buffer solution as mobile phase, Hypersil SAX column, flow rate: 0.8 mL/min, using UV detector at 195 nm wavelength to quantitative analysis glyphosate and N-(phosphonomethyl)iminodiacetic acid at the same column. The results showed that linear correlation for glyphosate and N-(phosphonomethyl)iminodiacetic acid were 0.999 9 and 0.998 4, the standard deviation were 0.089 9 and 0.770 1, the variation coefficient were 0.162 0% and 0.966 0%, respectively.
