Characterization and treatment of artisanal gold mine tailings
(2008)
The solid waste generated by artisanal gold mining, with high mercury and gold contents, can be found in several areas in the South America. The present study focused on the tailings of an artisanal gold mine area located ...
Thermal treatment of soils contaminated with gas oil: Influence of soil composition and treatment temperature
(Elsevier Science, 2002-10)
Samples of two soils containing different organic matter contents, neat or contaminated with gas oil (diesel fuel oil) at 2.5wt.% were heated from room temperature to different final temperatures (200-900°C). The experiments, ...
Microwave-assisted extraction through an aqueous medium and simultaneous cleanup by partition on hexane for determining pesticides in agricultural soils by gas chromatography: A critical study
(ELSEVIER, 2006-09-25)
A simple microwave-assisted extraction and partitioning method (MAEP) using water-acetonitrile and n-hexane for desorption and simultaneous partitioning, respectively, together with gas chromatography (GC) was studied to ...
Determinação multirresíduo de agrotóxicos em tomate, beterraba e cenoura empregando QuEChERS modificado e UHPLC-MS/MS
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2020-04-17)
Beet, carrot and tomato are foods with a high content of water, sugars and pigments, which are among the most cultivated and consumed vegetables worldwide and frequently contain pesticide residues. Therefore, a simple ...
Paper platform for determination of bumetanide in human urine samples to detect doping in sports using digital image analysis
(2019-06-01)
Development and application of a new, simple, inexpensive, and eco-friendly method is presented for the quantification of bumetanide in human urine samples for the detection of doping in sports. The method involves the use ...
Multiclass compatible sample preparation for UHPLC-MS/MS determination of aflatoxin M1 in raw milk
(Springer, 2015-10)
A sample preparation method for aflatoxin M1 (AFM1) determination in raw milk was optimized following the quick, easy, cheap, effective, rugged and safe (QuEChERS) strategy, as an alternative to the classic immunoaffinity ...
Multiclass Compatible Sample Preparation for UHPLC–MS/MS Determination of Aflatoxin M1 in Raw Milk
(Springer, 2016-09)
A sample preparation method for aflatoxin M1 (AFM1) determination in raw milk was optimized following the quick, easy, cheap, effective, rugged and safe (QuEChERS) strategy, as an alternative to the classic immunoaffinity ...
Determination of nitrotyrosine in Arabidopsis thaliana cell cultures with a mixed-mode solid-phase extraction cleanup followed by liquid chromatography time-of-flight mass spectrometry
(Springer Heidelberg, 2012-09)
In this work, a method for the determination of trace nitrotyrosine (NO2Tyr) and tyrosine (Tyr) in Arabidopsis thaliana cell cultures is proposed. Due to the complexity of the resulting extracts after protein precipitation ...
