Study on Fast Determination Method of Nitrite Pollution in Vegetable

YU Li-hong, KANG Li-juan, YU Xiao-bin, L Xiao-li (College of Resources and Environmental Sciences, Jilin Agricultural University, Changchun 130118, China)  
Using some vegetables sold in market as the experiment materials, based on the reaction that in a conc. sulfuric acid medium NO~-3 acting, as an oxidizing agent, reacts with salicylic acid, a method of fast determining nitrate pollution in vegetable was devised. Results of this method and those of Chinese standard method are in accordance. The determination process with this method requires twelve to fifteen minutes.
