Analytical Method for Determining Tetrazene in Soil
Abstract
An ion-pairing RP-HPLC method was developed to determine tetrazene in soil. The method involves extracting a 2-g soil sample with 50 mL of a solvent containing 55/45 v/v methanol-water and 1-decanesulfonic acid, sodium salt at 0. 01 M concentration. The soil and extracting solvent are vortexed for 15 s and shaken on a platform orbital shaker for a period up to 5hr. The extract is filtered through a 0.5-pm Millex SR filter and analyzed. Determination was achieved using an LC-18 column, a mobile phase of 2/3 v/v methanol-water containing 1-decanesulfonic acid, sodium salt at 0.01 M concentration, and a UV detector set at 280 nm. The mobile phase pH was adjusted to 3 with glacial acetic acid, which was optimal for separation of tetrazene form potential interferences by other explosives. Retention time was 2.8 min.
