Abstract: This paper reports that under ultrasonic wave complexing and extraction of Se-o-phenylene-diamine were finished simultaneously.With the aid of determination of ABSof toluene extracting liquid, the content of Se was determined.The best condition was the action of ultrasonic wave on the sample for 20-35 min.The average recovery was 98.2-98.3%.The pHrange was 1.7--1.9.

Key words: Ultrasonic wave, Selenium, o-Phenylenediamine
