It is known that the bio-materials are not only physically droken but also chemically degraded by ultrasonic irradiation. In this report, we try to degrate organnic phosphate using ultrasound. As the result, the mineralization of organic phosphate proceeded and phosphate ion was produced. After two-hour of sonication, about ninty percent of phosphorus was ionized. On long time sonication, however, it was difficult to detect phosphate ion. The inhibition of analysis by H2O2 produced from water was thought. This technique should be applied to the quantitative analysis of phosphorus in organic phosphate, after a several problems were solved.
