Resumen:
A method for glyphosate determination in β-cyclodextrin solution applying capillary electrophoresis was developed in order to supply an analytical tool to bioavailability studies. Experimental variables were optimized using univariant method and experimental design. The obtained linear range was 25 to 410 μg mL-1 and the detection limit of 4.4 μg mL-1. Real soil samples were treated with β-cyclodextrin solution to obtain working matrices. A recovery study is carried out on spiked real samples with good results (83 to 113 %).
