Determination of isoproterenol and uric acid by voltammetric method using carbon nanotubes paste electrode and p-chloranil

▶ p-Chloranil modified-carbon nanotube paste electrode used as a sensitive and selective voltammetric sensor for rapid analysis of isoproterenol in the presence of uric acid. ▶ Isoproterenol and uric acid in a mixture can be measured simultaneously and individually with a potential difference of 360 mV. ▶ The proposed sensor was successfully applied to the determination of isoproterenol in ampoule and urine samples.
