Application of a fully integrated photodegradation-detection flow-batch analysis system with an on-line preconcentration step for the determination of metsulfuron methyl in water samples

A critical review on photochemical conversions in flow analysis

“…Analyte photoconversion and detection at the same vessel is also feasible, as first demonstrated in a flow-batch procedure for metsulfuron methyl determination in waters [55]. In a mixing chamber, after irradiation at 240 nm for 30 s, the fluorescence of the degradation product of the herbicide was measured with excitation at 276 nm.…”

A simple voltammetric determination of metsulfuron-methyl in water samples using differential pulse cathodic stripping voltammetry

“…1) is a sulfonylurea herbicide in a small, white, granular form that can be used to kill broadleaf weeds and some annual grasses. [7][8][9] MSM can be utilized on various crops such as maize, wheat, rice, and soybeans. 7,10) Additionally, MSM is highly mobile in soil and moderately persistent in water, though it can enter water sources from field drainage or runoff water.…”

“…11) MSM can be easily degraded in acidic media, as well as in soils with high moisture content and high temperature. 12) The available literature reports that numerous methods, such as chromatography, 7,[13][14][15][16] capillary electrophoresis, 10,17) and spectrophotometry, 18) have been used for the determination of MSM. However, these methods are usually costly, time-consuming, and tedious, and they consist of a sample pretreatment step.…”
