Abstract: | A method is described for the determination of an organic tin insecticide, Vendex or hexakis(2-methyl-2-phenylpropyl)distannoxane (HMPD). Tin compounds are extracted from the sample homogenate with ethyl ether containing 1% acetic acid. HMPD and its degradation products are separated through a silica gel column, and analyzed by an atomic absorption spectrophotometer coupled with a heated graphite atomizer. By this technique, as little as 5 ng HMPD and its degradation products can be determined with an average recovery of 67-96%. |
