SIMULTANEOUS DETERMINATION OF ATRAZINE AND SODIUM DICLOFENAC IN NATURAL WATER BY SPECTROPHOTOMETRY APPROACHES

Diclofenac (DCF) and Atrazine (ATZ) are pollutants, present in natural waters. To develop new technologies for the abatement of these compounds, it is necessary to develop fast and low cost methods for routine quantification. In this work, two fast and accurate methods for the simultaneous determina...
