| Abstract: | Determination of water soluble phosphorous and effective phosphorous by extraction of triple superphosphate with ultrasonic cleaner was introduced, and effect of extraction factors on the result was studied. The method was simpler and quicker than the standard analytical method in HG/T 2219 - 2224 -91, with absolute deviation for the determination of water soluble and effective phosphorous between two methods both lower than 0.3, and the relative standard deviation was respectively less than 0.38% and 0.26%. |
