| Abstract: | Multiwavelength linear regression spectrophotometry combined with least square method is applied to the simultaneous determination of NO3 - and NO2 - in environmental water. By the choice of appropriate conditions, the absorbents are measured and the NO3 - and NO2 - can be calculated simultaneously .The datum obtained are compared with those obtained by maximum peak method, the result indicates that this method is the best one. |
