| 英文摘要 | A novel method for the determination of glyphosate by ligand-exchange chromatography was developed. baseline separation between glyphosate and(n-phosphonomethyl) iminodiacetic acid(pmida) as an intermediate has been carried out on a homemade column using 0.2 mmol/l cupric acetate-0.2 mmol/l acetic acid as a mobile phase, flow rate 0.8 ml/min and detection at wavelength 254 nm. the chromatographic conditions, such as concentration of cupric acetate and acetic acid in the mobile phase as well as the flow rate, have been optimized. the system suitability test and the analytical method validation has been completed under the optimal chromatographic conditions. the resolution rs between the glyphosate and pmida was found to be over 3 with the tailing factor t(f) from 0.8 to 1.0 and the correlation coefficients of glyphosate and pmida in the range of 0.05 - 1.00 g/l were 0.9998 and 0.9999, respectively. the recoveries, rsds of peak area and the limits of detection for glyphosate and pmida were 102.2% and 99.0%, 0.14% and 0.59% (n = 5), 0.05 and 0.50 mg/l(s/n = 3), respectively. |
