Dispersive micro-solid phase extraction using silica based sol-gel hybrid organic-inorganic material for analysis of organophosphorus pesticides in water samples
In 1930s, the insecticidal properties of organophosphorus pesticides (OPPs) and carbamate compounds were found and the compounds were developed for pesticides use in 1940s. They have been extensively used since 1970s when the environmentally persistent organochlorine pesticides were banned for use i...

In 1930s, the insecticidal properties of organophosphorus pesticides (OPPs) and carbamate compounds were found and the compounds were developed for pesticides use in 1940s.

The common method used for the analysis of pesticides is solid phase extraction (SPE) since it is more rapid, simple and economical than traditional liquid-liquid extraction.
