摘要：
Carbon electrodes with in situ electrodeposited copper are used to the determination of aminomethylphosphonic acid (AMPA), the major metabolite of the herbicide Glyphosate (N-phosphonomethyl) glycine) in drinking waters. The oxidation signal to form Cu(II) ions changes after the addition of AMPA due to the formation of a complex, this effect being used to develop an analytical method simpler, inexpensive and faster than those conventionally used. Glassy carbon and carbon paste electrodes are investigated, concluding that the last is more suitable for routine analysis. Samples of drinking water fortified with different AMPA concentrations have been used to test the method.
