Spectrophotometric method using Griess – Ilosvay reagent was established for determination of nitrite in water samples. The standard equation was determined. It is A = (0,71 ± 0,03).CN + (0,02 ± 0,01) with R2 = 0.99842. By this equation the values of LOD, LOQ of this method were calculated, where: LOD = 0.018 mg/L; LOQ = 0.062 mg/L. This method was used to determining nitrite concentration in Mekong river at Vientiane, Laos.
