| Description
| - This paper deals with a possibility of using Anion Exchange Resin in special equipment (probe) for the determination of phosphates and nitrates in surface water. Furthermore, this work presents the first results from a long-term measurement of the concentration of major pollutants in surface water, which are located in the area of our interest (CHKO Jizera Mountains). Six specials probes were prepared and placed in this area. These probes contained AER (AER -- Anion Exchange Resin, Type A520E -- Macroporous Strong Base Anion Exchange Resin with total capacity 0.9 eq/l), which were placed into special pockets. Each probe contained one pocket. This pocket was monthly changed. After the exchange, the concentration of nitrates and phosphates was determined. For the quantification of nitrates and phosphates trapped by the resin, the AER was dried at room temperature. Captured nitrates and phosphates were extracted from resin using 100 ml of 1.7 M NaCl. Released nitrates were determined by distillation and titration method. Released phosphates were determined by spectrophotometric method (Hach Lange No. 8048 in accordance with USEPA). Based on the findings, we can conclude that the application of AER to plastic probes is suitable for a quick and inexpensive measurement of the concentration of nitrates and phosphates in surface water. Moreover, differences in concentration of nitrates and phosphates were measured between individual probes. Concentration of these pollutants was significantly higher in watercourses that flowed through the villages than in water courses that flowed across the open country.
