A study of the photocatalytic degradation of metamitron in ZnO water suspensions

Desalination, 2009
Abstract The photocatalytic degradation of the herbicide metamitron in water using ZnO under Osram ULTRA-VITALUX® lamp light was studied. The effect of the operational parameters such as initial concentration of catalyst, initial metamitron concentration, initial salt concentration (NaCl, Na 2 CO 3 and Na 2 SO 4 ) and pH was studied.

Electrochemical reduction of metamitron

Journal of Electroanalytical Chemistry, 1998
Metamitron (I) (4-amino-3-methyl-6-phenyl-1,2,4-triazin-5(4H)-one) is a herbicide which is reduced electrochemically in two 2-e− steps. Reduction in the first step involves the protonated form of the 1,6-azomethine bond, while the second step involves the protonated form of the 2,3-azomethine bond. The 1,6-bond is reduced at potentials ca.

Novel electrochemical procedure for the determination of metamitron

International Journal of Environmental Analytical Chemistry, 2018
ABSTRACTIn this paper, a chronopotentiometric method for the determination of herbicide metamitron (MTM) using a glassy carbon electrode (GCE) and a thin film mercury electrode (TFME) as working electrodes is presented. MTM provided a well-defined reductive peak in the Britton–Robinson buffer on both working electrodes.

Field Dissipation of Metamitron in Soil and Sugar Beet Crop

Bulletin of Environmental Contamination and Toxicology, 2012
Bioaccumulation of herbicides in plant produce may cause ailing effect on animals and human beings through food chain contamination. Thus oblige the investigation of newer herbicide metamitron for its persistence and degradation in sugar beet crop and soil. Metamitron persist in plant up to 15 days while up to 30 days in soil.

Toxicokinetics, Recovery, and Metabolism of Metamitron in Goat

Journal of Agricultural and Food Chemistry, 2003
Toxicokinetic behavior and metabolism studies of metamitron and its effect on the cytochrome P(450) content of liver microsomal pellet were carried out in black Bengal goats after a single oral administration at 278 mg kg(-1) and consecutive oral administration of 30 mg kg(-1) for 7 days.

Influence of soil properties on the adsorption and mobility of metamitron

Communications in Soil Science and Plant Analysis, 1995
Abstract The adsorption and mobility of herbicide, metamitron, in 41 soils samples from the province of Salamanca (Spain) was studied. Thirty‐four of the samples assayed were from irrigated soils and seven were from natural, uncultivated soils with organic matter contents above 3%.

Polarographic study of the herbicide metamitron

Electroanalysis, 1994
AbstractThe electrochemical characteristics of the herbicide metamitron have been studied in the pH range 1 to 9 by applying several polarographic techniques, namely DCP, TAST, and DPP, adsorptive stripping voltammetry, and cyclic voltammetry with HMDE.

Determination and Method Validation of Metamitron in Soil by RP-HPLC

Bulletin of Environmental Contamination and Toxicology, 2013
A simple, rapid and economical method was developed and validated for the determination of metamitron using UV detector with RP-HPLC. Study of metamitron in soil was carried out. The compound was extracted from soil by methanol and clean-up was done on C-18 SPE column.

Oxygen dependence in the photoreaction of the pesticide metamitron

Journal of Photochemistry and Photobiology A: Chemistry, 2017
Abstract The dependence of the quantum yield of metamitron on oxygen concentration in the range c O 2  = (0.005–12.6)· 10 −4  M in aqueous solution was investigated with a polychromatic Xe-light source in the wavelength region 270–376 nm. The quantum yield of Φ = 0.022 ± 0.002 mol mol −1 at T  = (293 ± 3) K and c O 2 = 2.8
