摘要
介绍了采用超声波清洗器提取粒状三料重过磷酸钙中的水溶性磷和有效磷的测定方法及提取条件对测定结果的影响，该方法与HG／T2219～2224—91相比较，具有快速、简便的优点。水溶性磷的测定值与标准方法的绝对偏差〈0．3，RSD=0．38％；有效磷的测定值与标准方法的绝对偏差〈0．3，RSD=0.26％。
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%.
