| Abstract: | t present,there are many methods to determine the nitrate in environmental water,among these the phenol disulfonic acid luminosity method is widely used,but its operation is complicated.The presented method of ions selection electrode to determine the nitrate is simple and precise the interference ions in the water sample are easy to remove,the recovery ratio of sample is high.Facts proved this method is practicable. |
