Discrimination Method of Glyphosate-potassium AS by Ion Chromatography
The discrimination method of glyphosate-potassium AS was established by Ion Chromatography (IC) using 5 mmol/L methanesulfonic acid aqueous solution as the mobile phase,CS 12A ion column (including CG 12A guard column) and conductivity detector. The results showed that the linear correlation coefficient of the method was 0.9999, the standard deviation was less than 0.1, the coefficient of variation was less than 1.0%, the average recovery was 100.65%. The method was precise, accurate and simple, could be used to discriminate the active ingredient in glyphosate- potassium AS.
