Determination of Copper-Based Fungicides by Flame Atomic Absorption Spectrometry Using Digestion Procedure with Sulfuric and Nitric Acid
Copper-based fungicides can be effectively digested by treatment with a mixture of
concentrated sulfuric and nitric acid in exactly 15 minutes for the rapid determination via
copper using flame atomic absorption spectrometry ...
Headspace Solid Phase Microextraction in Pesticide Residues Analysis: 1. Optimisation of Extraction Conditions
The method of headspace solid phase microextraction (HS/SPME) was successfully
used in a simultaneous multicomponent analysis of hexachlorobenzene (HCB), tefluthrin,
heptachlor, aldrin, chlorpyrifos, fenthion and bifenthrin ...
Headspace Solid Phase Microextraction in Pesticide Residues Analysis: 2. Apple Samples
Headspace solid phase microextraction method (HS/SPME), optimised previously for
pesticide water solutions, was applied to trace residues of the pesticides chlorpyrifos, fenthion
and bifenthrin in apple samples. One-hour ...
