【求助】求助！菇类中磷化铝残留的检测方法

楼主，你好！《GB/T 5009.36-2003 粮食卫生标准的分析方法》中对磷化物有测定方法：
4.3.2.1 原理
磷化物遇水和酸，放出磷化氢，蒸出后吸收于酸性高锰酸钾溶液中被氧化成磷酸，与钼酸铵作用生成磷铝酸铵，遇氯化亚锡还原成蓝色化合物钼蓝，与标准系列比较定量。
您可以参考一下。

Determination of Aluminum Phosphide in Fumigants
CHUAN KAO
Journal of Food Science; Volume 46 Issue 5, Pages 1632 - 1632

ABSTRACT:
A simple method has been developed to measure aluminum phosphide (AlP) in fumigants. Phosphide-containing fumigants were reacted with water to release phosphine gas (PH₃), and the gas was oxidized to phosphate by permanganate. The phosphate formed was then determined by the gravimetric quinolinium molybdophosphate method (AOAC, 1975).

这个物质好像只能用间接方法测定吧，通过铝或磷来测定。
