本文研究了１－羟基－４－（对甲苯胺基）－蒽醌（ＨＰＴＡ）与硼的显色反应．实验表明：该显色反应灵敏度高，选择性好。该法用于Ａｌ－Ｔｉ－Ｂ合金中硼的测定，获得满意的结果。
In this paper, the color reaction of 1-hydroxy-4- (p-toluidino) -anthraquinone (HPTA) with boron was studied. Experiments show that the color reaction has high sensitivity and good selectivity. The method was applied to the determination of boron in Al-Ti-B alloy, and satisfactory results were obtained.
