Use of liquid chromatography for the determination of mass concentration of glycerintrinitrate in industrial wastewaters

Resumo

The process waters of the filled polymers production are subjected to the purification from specific components before their disposal into sewer-pipe drains. One of such components is glycerintrinitrate. In order to evaluate the purification level from glycerinetrinitrate by different methods it was necessary to develop an express method for the component analytic control. The problem was solved by the liquid chromatography method. The method for determination of glycerintrinitrate mass concentration in process and purified waters in the range of 11 to 220 mg/dm³ was developed. The usage of the method developed allowed to define an efficient method of the process waters purification from glycerintrinitrate and to select the optimal technological process parameters.
