Application of Stratified System Water - Antipyrine - Sulfosalicylic Acid in the Chemical Monitoring of Nitrite Ions

Nitrite ions are labile toxicants for natural systems, drinking water and food.
Aim of this research is to demonstrate the possibility to extract nitrite ions from water solutions by the system water - antipyrine - sulfosalicylic acid for stabilization and concentration. This study shows the efficiency of extraction of nitrite ions by bottom system water - antipyrine - sulfosalicylic acid. By means of concentrating nitrite ions "in situ" using methods "added-identified" and spectrophotometry on model systems the researchers determines the degree of extraction (96,3 ± 0,3%) and concentration factor (129 ± 5) for nitrite-ions.
Key words: bottom system, organic phase, nitrite ions, the extraction.
