摘要
试样以酸溶解,在硫磷溶液介质中,加入氟化氨与硼生成氟硼络离子（BF-4）,加入次甲基蓝与之生成蓝色络合物,用二氯乙烷萃取后,以光度法测定。测定范围：硼含量0.000 5－0.05%的碳钢、低合金钢、高合金钢。
Sample is dissolved in acid,moved into sulfuric acid and phosphorus acid medium,added to fluoric ammonia and forms blue chelate（BF-4） which is extracted with 2-chloroethene and determined by colorimetry.
