Abstract

Ultrasonic assisted CPE was used for the preconcentration of sulfite. The effect of foreign ions which may be present in actual samples was investigated. The method was applied to the quantification of sulfite in vegetables and dried fruits. The analytical variables affecting UA-CPE efficiency were optimized. The enrichment factor 95 was obtained.
