摘要
用盐酸溶解试样,碳酸钡分离干扰离子,蒸干、显色,硼与姜黄素生成红色化合物,在540nm处测其吸光度,采用姜黄素比色法测定测定大理岩中低含量的硼,方法简便、快速、准确度高,能满足生产检测要求。
With the hydrochloric acid dissolution test specimen,the barium carbonate separation disturbance ion, steams does, thecoloration, the boron and the ginger flavine production red compound, in 540nm place measured it attracts the luminosity.
