Since the widespread presence of metal ions in ecosystem, especially heavy that could bring severe damage to living organisms, development chemosensors for is high demand. In this contribution, we designed and synthesized a new corrole-based covalent organic framework (CorMeO-COF) with good crystallinity porosity. CorMeO-COF can detect Cu(II) sensitivity selectivity based on efficient fluorescence quenching caused by photoinduced electron transfer (PET) process. More interestingly,...
This study reports the development and validation of a novel rapid cleanup method based on multiple-walled carbon nanotubes in packed column filtration procedure for analysis pesticide residues followed by gas chromatography–triple-quadruple tandem mass spectrometry detection. The was carried out applying streamlined multiplug with syringes. sorbent used removing interferences matrices is mixed anhydrous magnesium sulfate. proposed convenient time-saving as it does not require any solvent...
A multiresidue method for determining pesticides in rapeseed, rapeseed oil, and meal by use of liquid chromatography-tandem mass spectrometry is developed. Samples were extracted with acetonitrile or acidified cleaned up a 12 h freezing step. The recovery data obtained spiking blank samples at three concentration levels. recoveries 27 selected the range 70-118%, level 10 μg kg(-1), intraday interday precisions lower than 22 27%, respectively. Linearity was studied between 2 500 L(-1)...
Construction of a novel two-dimensional covalent organic framework with excellent photoluminescence performance using flexible building blocks.
This study reports the development of a novel multiplug filtration cleanup (m-PFC) procedure for analysis pesticide residues in leek samples followed by gas chromatography-tandem mass spectrometry detection. The were initially purified following dispersive solid-phase extraction with different sorbents to determine most suitable proportioning sorbent materials; then, m-PFC method was carried out applying streamlined syringes. Average recoveries pesticides range from 70.2 126.0% relative...
Spinach is one of the most commonly planted vegetables worldwide. A high chlorophyll content makes spinach a complicated matrix in pesticide residue analysis. In this study, rapid clean-up method was developed for analysis multi-residues followed by liquid chromatography with tandem mass spectrometry. modified QuEChERS multiwalled carbon nanotubes and material adopted multi-Plug Filtration Cleanup procedure. This validated 44 representative pesticides spiked at two concentration levels 10...
Direct analysis in real time (DART) is a new ion source technique, which conducted the open air under ambient conditions, applied to rapid and direct of any material (gases, liquids, solids) with minimal or no sample preparation. In order take advantage capacity DART mass spectrometry for real-time hazardous ingredients commercial agrochemicals, pilot study qualitative determination pesticides was performed.Highly were identified by ionization coupled single-quadrupole spectrometer...
To reduce labor-consuming manual operation workload in the cleanup steps, an automated multiplug filtration (m-PFC) method for QuEChERS (quick, easy, cheap, effective, rugged, and safe) extracts was developed. It could control volume speed of pulling pushing cycles accurately. In this study, m-PFC based on multiwalled carbon nanotubes (MWCNTs) mixed with primary-secondary amines (PSA) anhydrous magnesium sulfate (MgSO4) a packed column analysis pesticide residues followed by gas...
Abstract BACKGROUND Plant protection products (PPPs) are applied in China and many other developing countries with knapsack sprayers at high volumes coarse spray quality, resulting a percentage of pesticide losses. In this study, new air‐assisted electric sprayer two conventional were evaluated terms deposition, residues loss into the soil. Artificial targets fixed to upper side underside leaf surface six zones (at depths three heights) used collect which analyzed by liquid chromatography...
A method based on disposable pipet extraction (DPX) sample cleanup and gas chromatography with mass spectrometric detection by selected ion monitoring (GC/MS-SIM) was established for 58 targeted pesticide residues in soybean, mung bean, adzuki bean black bean. Samples were extracted acetonitrile concentrated (nitrogen flow) prior to being aspirated into DPX tubes. Cleanup procedure achieved a simple DPX-Qg tube. Matrix-matched calibrations analyzed, the limits of quantification (LOQ) this...
