挥发酚测定方法的改进

An Improvement in the Method of Assaying Volatile Phenols

对测定挥发酚的试剂4—氨基安替比林溶液提出了一种新的配置方法,通过加入三氯甲烷进行萃取,降低了空白实验,达到了国家标准规定的最低检出限0.002的要求,并对该方法的准确度和精密度进行了验证.结果表明,此方法准确可靠,在样品监测工作中优于原方法.

A new collocating method about the reagent of 4-aminoantipyrine liquor in assaying volatile phenols is proposed.Blank checks are reduced.The accuracy and preciseness of the new method are proved.Its reliability is ascertained and its results are more accurate than that of the original method in assaying routine samples.
