用4-AAP萃取光度法测定挥发酚的几点体会

介绍了在测定挥发酚过程中对试剂的保存、缓冲溶液pH值的控制、各种试剂的加入顺序及萃取时间的确定等问题的几点体会,并有针对性地提出了解决的办法。

This paper introduces the process in the determination of volatile phenol reagent in the preservation of the buffer the pH value of the control sequence of the addition of reagents and extraction time issues such as the determination of the points of, and in a targeted manner to the solution to the problem.
