摘　　要：采用水杨醛与H-酸钠盐在发色时与硼临时合成产生的显色反应光度测定硼。结果表明,显色速度加快,在30min内发色完全。显色体系硼的质量浓度介于2～20μg/mL之间,遵守比尔定律。本方法简便快速,准确度和精密度能满足监测分析要求。Boron was determined by chromogenic reaction photometry of boron and salicylaldehyde and Sodium H-acid. Results showed the chromogenic reaction finished in 30min for chromogenic rate was speeded up. Beers law was obeyed while the weight concentration of boron in chromogenic system was in the range of 2 - 20 μg/mL. The method was simple and rapid, and the accuracy and precise of analytical result could meet the requirement of monitoring analy-
