| Popis: | Nitrate concentration (2–100 μg NO 3 -N1 −1 ) in water samples as small as 5 ml can be determined manually in test tubes by a modification of the standard cadmium reduction method without loss of sensitivity. Once reaction tubes are prepared, 30 samples can be batch-processed in one hour by this technique. Reaction tubes can be used 5–10 times before the reactivation of the cadmium is necessary. |
