摘要: The electrochemical behavior of a sonogel-carbon electrode towards nine phenolic compounds (chloro-, nitro- and alkyl-phenols) was studied; one them (4-chloro-3-methylphenol) used to evaluate characteristics the electrode, such as accumulation cleaning procedure surface, reproducibility measurements, influence time from fabrication on response. A polyethyleneglycol-modified found improve response analyte. linear relationship between peak height concentration in range 0.005–0.5 mg L−1 obtained, with detection limit 2.8 μg L−1. studies parameters, well interferences, are also included.
