Abstract: PURPOSE: A simultaneous detection method of Glyphosate, Endothall and Chloramben as herbicides in water samples is provided, thereby easily, accurately and cheaply detecting the herbicides at one time. CONSTITUTION: A simultaneous detection method of Glyphosate, Endothall and Chloramben as herbicides in water samples comprises the steps of: concentrating Glyphosate, Endothall and Chloramben and forming their derivatives with anhydrous trifluoroacetic acid and trifluoroethanol; analyzing their derivatives to prepare a measuring curve for determination of the concentrations of three herbicides; forming derivatives of three herbicides in various environmental samples; and determining the concentrations of three herbicides, wherein the concentration is carried out by using vaporization under vacuum; the formation of derivatives of three herbicides is carried out by heating the mixture of herbicides with trifluoroacetic acid and trifluoroethanol at 60 to 90 deg. C for 30 to 120 minutes; and the concentration of three herbicides is determined by using gas chromatography/mass spectrometer.

Abstract: PURPOSE: A method of concurrent-detecting micro acid pesticides is provided to concurrently extract and detect ten kinds of pesticides from the samples of water or soil in an effective manner. CONSTITUTION: In a method of co-detecting micro acid pesticides, samples are taken from the water or soil, and a strong-base material is added to the samples to make a mixture. The mixture is bathed, and hydrolyzed. The mixture is acidified by a strong acid solution, and the target is extracted from the acidified mixture by using an organic solvent. The extract is derivatized in reaction with trifluoro acetic acid anhydride and trifluoro ethanol. The derivatized extract is directly put in a gas chromatograph, or a gas chromatograph/a mass spectrograph to concurrently detect the micro acid pesticides.
