摘要
文章对两种测定NO_3^--N的方法从灵敏度、去Cl^-、NO_2^-的干扰能力及实际操作作了比较,并提出了用麝香草酚测定NO_3^--N应注意事项。
In this paper,a comparision between the spectrophotometric methods to determine NO3 -N in water by thymol and phenol disulf onic acid were made. In spite of the sensitivity of the methods of phenol disulf onic acid is better than that of thymol, the thymol method possesses good ability to diminish the interference of Cl- and NO2- .and is easier to operate. Some attention to carry out the thymol method was given.
