| An automated monitoring system for nitrite, nitrate and sulfate based on sequential injection analysis (SIA) was developed. For nitrite determination the Griess-Ilosvay method was used, whereas nitrate was previously reduced to nitrite using a cadmium column followed by the same method. The turbidimetric method was carried out in order to determine sulfate. The results shown that the proposed SIA monitoring system constitutes an effective approach for nitrite, nitrate and sulfate determination since it is able to determine levels required by international agencies that regulate these parameters in water. Detection limits of 0.0207 mg N l-1, 0.0022 mg N l-1 and 3 mg SO4 2- l-1 were obtained. The developed technique offers also typical characteristics of the multicommutated systems, as portability, low reagents consumption and a higher sample frequency. The proposed system was satisfactorily applied to drinking water and wastewater samples. | |
