Atomic absorption spectrometric determination of cyhexatin in apples.

A rapid method using atomic absorption spectrometry has been developed for determining residues of cyhexatin in apples. Each analysis takes less than 30 min and the method is sensitive to less than 0.1 mg cyhexatin/kg. Recoveries varied from approximately 100% at 0.25 and 0.05 mg/kg to 70% at 5 mg/kg. No acid digestion or cleanup is required for the analysis.
