一、前言目前铝合金中硼量的测定,大多采用洋红比色法和蒸馏分离-姜黄素比色法。洋红比色法的灵敏度及准确度均较低,且要在浓硫酸条件下进行发色,操作非常不便。而后者需经繁杂的分离手续,分析周期较长,并且要使用有机 First, the preface At present, the determination of boron in aluminum alloy, mostly using magenta colorimetric separation and distillation - curcumin colorimetric method. The sensitivity and accuracy of the magenta colorimetric method are low, and hair color in concentrated sulfuric acid conditions, the operation is very inconvenient. The latter need to go through a complicated separation procedures, analysis cycle is longer, and to use organic
