Abstract

SANDOVAL, BABILYN C. University of the Philippines Los Banos. March, 1995. Development of Rapid Method for the Detection of pyrethroid insecticide Residues:Deltamethrin

Adviser: Dr. Amelia W. Tejada Rapid method for the detection of pyrethroid group of insecticides was developed using micro thin chromatography.

Response of pyrethroid to various kinds of adsorbents, developing solvents and chromogenic reagents was investigated. Among the different TLC tested, silica gel 60 (IF incorporated with one silver nitrate as adsorbent, and 1,,ane chloroform (60:40) as developing solvent gave inn results. The minimum detectable limit is 0.125 ug deltamethrin. Vegetable sample spiked with deltamethrin was analyzed using this technique.

The developed technique was package into a 1. This consists of the precoated plates extracting solvent, vial for extraction developing of developing chamber, capillary tube, forceps the alcohol lamp and matches.

The package kit is specific for deltamethrin. This can also detect other halogenated pyrethroid upon to shortwave UV light.
