Hollow Fibre Membrane-Protected Molecularly Imprinted Microsolid-Phase Extraction (HFM-Protected-MI-MSPE) of Triazines from Soil Samples

Separations, 2018
In this work, a combination of molecularly imprinted polymer (MIP) technology with micro solid-phase extraction in a hollow fibre device is described. MIP microspheres were synthesized and packed into polypropylene hollow fibre (HF) segments.

Collaborative Study of a Gas-Liquid Chromatographic Method for the Analysis of Propazine

Journal of AOAC INTERNATIONAL, 1975
Abstract A gas-liquid chromatographic method for the determination of propazine in wettable powder formulations containing about 80% active ingredient was collaboratively studied, using a matched pair scheme. The propazine was extracted from the powder with chloroform, with dieldrin as an internal standard, and chromatographed on ...

On the removal of s-triazine herbicides from waters using commercial low-cost granular carbons [PDF]

Journal of the Serbian Chemical Society, 2010
The adsorption capacities of three low-cost granular active carbons, used in a water treatment facility for the removal of the triazine herbicides propazine, prometryn and prometon, was evaluated. Kinetic studies showed that the three carbon samples used

Sorghum tolerance and weed control with amicarbazone and metribuzin applied preemergence

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Groundwater contamination has prompted the Environmental Protection Agency to consider restricting atrazine use, highlighting the need for alternative preemergence herbicides in grain sorghum (Sorghum Moench). Research was conducted in 2023 and 2024 to evaluate grain sorghum tolerance and weed control from preemergence applications of ...

Advanced Sorbent Materials in Solid‐Phase Extraction: A Decade of Innovation and Future Perspectives

Chemistry–Methods, Volume 6, Issue 8, August 2026.
This review systematically summarizes five families of advanced sorbent materials for solid‐phase extraction (SPE): nanocarbons, porous frameworks (MOFs/COFs), smart polymers, biomass‐derived sorbents, and multifunctional composites. Key molecular interactions (π–π stacking, hydrogen bonding, electrostatic attraction, host–guest recognition) are ...
