| Abstract: | A new method is set up to determine the water-soluble and available phosphorus in diammonium phosphate by the application of ultrasonic wave to solve the sample. The factors that will affect the solving result have been analyzed and determined. The time of sample solving is shortened from 8-12 hours to 30 min. The precision and accuracy between the new method and the classic method have no significant difference. |
