Jatropha crude oil was pretreated with microwave digestion technology, and then phosphorus content was determined. Appropriated conditions of microwave digestion were selected. Precision of test method was analyzed. De-termination results with microwave digestion were contrast with results with dry digestion. And sample standard recovery rate experiments were carried out. Results showed that microwave digestion method had some advantages, like simple, reagent consumption and good reproducibility. Sample preparation time with microwave digestion technique could greatly reduce. This method applies to rapid analysis of jatropha crude oil phosphorus content.
