Comparative evaluation of various extraction techniques for analysis of Hexaconazole residues in Soils

Abstract

The extraction of hexaconazole (fungicide) residues from the soil samples was conducted by noval extraction techniques like ASE along with traditional methods like soxhlet, column and mechanical shaking. The samples have been collected from different agro-climatic zones of Uttar Pradesh region. The analysis was performed without clean-up by HPLC. The results showed that the ASE and HPLC techniques are clearly faster, more sensitive and more cost effective than conventional methods. The recovery efficiency of ASE was above 90% in all studies.
