This paper reports the use of polished silver solid amalgam electrode (p-AgSAE) allied to square wave voltammetry (SWV) in development a simple, sensitive, fast and green electroanalytical methodology for trifluralin herbicide determination fresh food samples. The experimental (supporting electrolyte potential time accumulation) voltammetric (pulse frequency, pulse amplitude scan increment pote...

Trifluralin is one of the most widely used herbicides, being accounted as cause cancer in human. In present research, UV/S2O82? and ZnO/UV processes’ efficiency removal trifluralin was investigated. A lab scale equipped with a UV lamp applied. The parameters were studied, including initial concentration (0.4–1.2 mg/L), contact time (20–60 min), S2O82? ?M), ZnO (50–150 mg/L). remained measured b...

Agricultural solid waste (corn cob) has been investigated asbiosorbent for removal of metribuzin herbicide from aqueous solution. Parameters influencing extraction efficiency such as pH of the sample, contact time of sample with biosorbent, shaking time, temperature, heating time, sorbent dose were studied. Maximum sorption of metribuzinwas found at pH 5.0. The sorption of metribuzin on corn co...

Among agricultural pesticides, herbicides comprise the most employed group in agriculture. The main function of these chemicals is to control weeds, weed competition reduces produc‐ tivity, without significantly impacting crop yield. Weeds tend to compete with crops by extracting essential elements from the soil, water, intercepting light and CO2, interfering in the culture development and affe...

The addition of organic manure affects the biological, chemical and physical properties of soil that control the fate of herbicides. Three dinitroaniline herbicides were studied to asses their persistence, dissipation and residue management in sandy loam soil with and without addition of farmyard manure (FYM) under middle western Indian agro-climatic conditions. The herbicides, pendimethalin [N...

Greenhouse studies were conducted in 2008-2009 with the objective of adjusting dose-response curves of the main soil-applied herbicides currently used in cotton for the control of Amaranthus viridis, A. hybridus, A. spinosus, A. lividus, as well as comparing susceptibility among different species, using the identity test models. Thirty six individual experiments were simultaneously carried out ...

As part of a project funded by the European Commission (EC) for the development and evaluation of multiresidue methods for analysis of drinking and related waters, 15 European laboratories evaluated a method using styrene-divinylbenzene co-polymer solid-phase extraction followed by gas chromatography/mass spectrometry. The main aim of the study was to evaluate whether the method meets the requi...
