本文作者提出用次亚磷酸钠为标准品,作体内磷化氢的定量测定。探讨了采用气相色谱法、硝酸银比色法及AgDDC分光光度法定量测定体内磷化氢的条件及其线性范围。作者认为,此法有两个优点:一是可避免将磷化氢氧化成磷酸根的繁琐操作;二是简化了定量方法。
The authors propose the use of sodium hypophosphite as a standard for quantitative determination of phosphine in the body. The gas chromatography, silver nitrate colorimetry and AgDDC spectrophotometry were used to quantitatively determine the conditions and linear range of phosphine in the body. The authors believe that this method has two advantages: First, to avoid the cumbersome phosphine oxidation of phosphine; the second is to simplify the quantitative method.
