Detection Of Hazardous Substances In Tobacco Exogenous Technology And Application Research

Pesticide residues, heavy metal pollution is an important factor of safety hazards tobacco, strengthen tobacco pesticide residues, heavy metals and other hazardous substances detection, monitoring, control, to increase tobacco security an important way.Using solid-phase extraction by gas chromatography (GC) detection tobacco organochlorine and pyrethroid pesticide residues, solid phase extraction by gas chromatography (GC) detection tobacco oranophosphorous residues, solid phase extraction gc-ms method to detect tobacco triadimefon pesticides, through the recovery rate and precision, the experimental results, the ideal, high efficiency, and good effects. Use wet digestion, the hydride atomic fluorescence spectrometry (-) method HG commercol - AFS arsenic in tobacco, with nitric smoke microwave digestion system -- hydrogen peroxide, hg-afs (AFS) detection tobacco HG commercol - the content, the necessary equipment HG commercol low price, high sensitivity, the method is simple, rapid, is a kind of very good method.
