Digestion Efficiency during Alkaline Persulfate Oxidation for The digestion is strongly alkaline at the outset, which promotes oxidation of nitrogen to nitrate. The filter on colorimeter is 550 nm. Quantifying total phosphorus contents of organisms can elucidate their physiological condition and the nutrient cycles of ecosystems. Using an eye dropper, fill pump tube with prepared cadmium. Settings on the Houston Omniscribe are as follows: -Nitrate module: Total nitrogen is analyzed as nitrate after digestion. Calculate the N andP concentrations as shown below. To protect the cadmium from exposure to air, cover the cadmium granules with ammonium chloride solution. Water samples and standards are autoclaved in an alkaline persulfate digestion solution. Phosphorus, frequently identified as a nutrient limiting primary production, is responsible for algal blooms and invasions of exotic species in most surface water ecosystems.
