“…The square-wave electrochemical mode offered favourable signal-to noise characteristics and was used by Sarigul & Inam (2009) for determination of cyclosulfamuron in tap water and soil achieving LODs of 3.1 µg/L and 2.3 µg/L, respectively.…”

“…Capillary electrophoresis (Blasco, Pico, and Andreu 2009;Hernandez et al 2004Hernandez et al , 2005 and photocatalytic degradation (Goutailler et al 2001) have also been studied. Electroanalytical techniques such as voltammetry, amperometry, and polarography are characterized by simplicity, sensitivity, costeffectiveness, precision, and accuracy; as a result, they have been used for the determination of pesticides (Qiu and Ni 2008;Sarıgü l and İnam 2009).…”

The electrochemical behavior of cyromazine (N-cyclopropyl-1,3,5-triazine-2,4,6 triamine) insecticide has been studied at newly prepared multi-wall carbon nanotubes paste electrodes using square wave stripping voltammetry. The cyromazine was accumulated at 0.0 mV [vs. Ag/AgCl (3 M NaCl)] and a well-defined anodic peak obtained at þ1110 mV in 0.1 M H 2 SO 4 . The cyclic voltammetric measurements showed an irreversible nature of oxidation wave in the range of scan rates comprised between 500 and 4000 mV s À1 . The calibration curve obtained from square wave stripping voltammetry was linear in the range 0.41 to 83.30 lg/mL with a detection limit of 0.12 lg/mL. The method was applied to the direct determination of cyromazine in natural water samples. Recoveries calculated for river and tap water samples spiked with 10.0 lg/mL level were 101.5 AE 1.9% and 100.6 AE 2.3% at 95% confidence level, respectively. The method was extended to the determination of cyromazine in agrochemical formulation Trigard 1 with a recovery of 100.49% and accuracy was in agreement with that obtained by HPLC comparison method. Influences of some interfering ions and pesticides were also investigated.

“…Electrochemical methods, e.g., polarography, voltammetry, and square wave voltammetry are used to determine either organic 15, 16 or inorganic 17 electroactive species. The limitations of electroanalytical procedures and their advantages compared to HPLC and GC, such as speed, sensitivity, and speciation were elsewhere discussed by Zuman 18.…”

Cyanuric acid is a suspected gastrointestinal or liver toxicant in humans. Therefore, determination of trace cyanuric acid is very important, in this work a novel, sensitive, and reliable method was developed using differential pulse polarography. Optimum conditions for analytical determination were found to be at a pH of 9.5, BrittonRobinson at a reduction potential of À105 mV. Experimental results indicate an excellent linear correlation between the peak current and the concentration in the range of cyanuric acid from 0.5 to 27.0 mM (0.06-3.5 mg mL À1 ) with a correlation coefficient of 0.997. The limit of detection and limit of quantification were obtained as 0.15 and 0.5 mM (0.02-0.06 mg mL À1 ), respectively. The proposed method was successfully applied to the determination of cyanuric acid in pool water and in spiked milk. Cyanuric acid level in swimming pool water was found as 2.54 AE 0.47 mg mL À1(19.7 AE 2.29 mM) in swimming pool water for N ¼ 4 and 95% confidence interval. The recoveries were found to be sufficient. Also, the standard deviation of the data was low which shows high accuracy and precision of proposed differential pulse polarographic method. The influences of some other commonly found inorganic salts on the determination of cyanuric acid were also examined. Some interfering species were eliminated using complexing agents, e.g., EDTA.
