| Abstract: | The comparison analysis of nitrate nitrogen determination is conducted with the same standard solution and natural water samples by two methods of spectrophotometric method with phenol disulfonic acid and ultraviolet spectrophotometer. The results show that ultraviolet spectrophotometer is more convenient to operate with less chemical reagent pollution and in -time to get the data, which is a prior method. |
