dc.descriptionIn this work, two methods were developed to determine herbicides paraquat, glyphosate, and aminomethylphosphonic acid (AMPA) in marijuana samples by capillary electrophoresis. For paraquat analysis, sample was extracted with aqueous acetic acid solution and analyzed by capillary zone electrophoresis with direct UV detection. The running electrolyte was 50mmol/L phosphate buffer (pH 2.50). For glyphosate and AMPA, indirect UV/VIS detection was used, as these substances do not present chromophoric groups. Samples were extracted with 5mmol/L hydrochloric acid. The running electrolyte was 10mmol/L gallic acid, 6mmol/L TRIS, and 0.1mmol/L CTAB (pH=4.7). The methods presented good linearity, precision, accuracy, and recovery. Paraquat was detected in 12 samples (n=130), ranging from 0.01 to 25.1mg/g. Three samples were positive for glyphosate (0.15-0.75mg/g), and one sample presented AMPA as well. Experimental studies are suggested to evaluate the risks of these concentrations to marijuana user.
