分光光度法快速测定ABC灭火剂中的磷酸二氢铵和硫酸铵含量

Rapid Quantitative Analysis of NH4H2PO4 and （NH4）2SO4 in ABC Powder Extinguishing Agent

为了满足消防产品中灭火剂的现场快速检测需求,提出利用钼锑抗分光光度法和纳氏试剂分光光度法快速测定ABC灭火剂中主要组分磷酸二氢铵和硫酸铵含量的新方法。与现行国家标准方法相比,该方法具有快速、简便、准确的优点,适合灭火剂产品的现场快速检测。

In order to meet the requirement of present rapid detection of fire product extinguishing agent,a new quantitative method to determine NH4 H2 PO4 and(NH4)2 SO4 in ABC powder extinguishing agent using Mo-Sb Anti-spectrophotometry and Nessler’s reagent spectrophotometry was proposed.Compared with the present standard method,this method has the characteristics of rapidness,easy operation and accuracy,which is suitable for the rapid quantitative analysis of the fire products on site.
