Communications Recovery of DDT and Dieldrin from Tissues of Coturnix Japonica Stepwise During Residue Analysis

Abstract

▪ Recoveries were measured stepwise during a 5-part analytical procedure by counting carbon-14 labeled p,p′-DDT or dieldrin. The greatest losses occurred during concentration of eluates from Florisil columns or zones from thin-layer plates and were probably due to codistillation. Nonetheless, overall recoveries of 70–94 % are possible. © 1970, American Chemical Society. All rights reserved.
