“…The degradation efficiency of some organic materials was significantly enhanced with the presence of NaCl in some researchers [2,15,26]. In the present experiment, three different NaCl dosages of 0.1, 0.2 and 0.5 g•L -1 were added into the ChS solution for ChS electrochemical degradation.…”

“…Their broad spectrum of action with a low application dose has led to a rapid acceptance of these compounds. However, their high phytotoxicity and relatively high solubility make them potential contaminants of groundwaters [2,3]. Furthermore, sulfonylurea compounds which are used as herbicides for agriculture undergo decomposition into, among others, simpler sulfonamides.…”

Chlorsulfuron (ChS) which is a nonbiodegradable herbicide was effectively removed using an electrochemical method at the Ti/IrO 2-Pt anode. The influences of current density, initial ChS concentration, initial solution pH and different NaCl dosages on electrochemical degradation of ChS were investigated. HOCl formed during electrolysis and quickly generated •OH radicals would likely play an important role in the electrochemical degradation of ChS with the presence of NaCl. At current density of 20 mA•cm-2 , ChS concentration decreased from 1 mg•L-1 to 0 mg•L-1 after 10 min electrolysis with 0.2 g•L-1 NaCl dosage. It was found that the ChS removal rate increased with increasing current density and the ChS degradation was similar at different initial pH values, which means that Ti/IrO 2-Pt anode can be used in a wide pH range. The electrochemical performance of Ti/IrO 2-Pt anode for degradation of ChS will not decrease after serviced for a long time. These results reveal that an electrochemical approach would be a novel treatment method for effective and rapid degradation of ChS herbicide from aqueous solution.

A multiwall carbon nanotube paste electrode (MWCNTPE) was fabricated to investigate the detailed electrochemical behavior of methacetin and achieve its sensitive electroanalytical determination. The sensitive and selective square wave anodic peak seen at +1.06 V was linearly related to methacetin concentration in the range of 0.11 to 22.3 mg L À1 [0.665 to 135 mM]. The limit of detection (LOD) and the limit of quantification (LOQ) were 0.032 mg L À1 [0.193 mM] and 0.11 mg L À1 [0.665 mM],respectively. The percentage recovery of methacetin calculated from natural lake water samples spiked at the 5.0 mg mL À1 [30.3 mM] level was 94.2% with a relative standard deviation of 0.21%. The considerably high recoveries and low standard deviations were evidence for the high accuracy and precision of the recommended method. The recovery of 10.0 mg mL À1 [60.5 mM] methacetin in the presence of the same concentrations of other pesticides such as benzanilide, propanil, tribenuron methyl, rimsulfuron, metsulfuron methyl and chlorsulphuron ranged from 89.2% to 98.3%. The oxidation peak of 10 mg L À1 [65.3 mM] dopamine appeared at +0.740 V(vs. Ag/AgCl) and did not display a significant interfering effect, therefore methacetin and dopamine could be simultaneously determined.

A review of literature published in 2010 on analytical methods for pesticides and herbicides is presented here in eight sections, including extraction methods, chromatographic or mass spectrometric techniques, electrochemical techniques, spectrophotometric techniques, chemiluminescence and fluorescence methods, sensors, biochemical assays and immunoassays, and miscellaneous techniques. Because many of the research studies in the cited publications utilized more than one analytical method, the different sections should not be thought of as being mutually exclusive.
