Total phosphorus in water: Under neutral conditions, dissolve the sample with potassium persulfate (or nitric acid perchloric acid) to oxidize all the phosphorus to orthophosphate. In an acidic medium, orthophosphate reacts with aluminate to form a phosphoaluminate heteropolyacid in the presence of antimony salt, which is immediately reduced by ascorbic acid to form a blue complex.
Total nitrogen in water: At 120-124 ° C, an alkaline potassium persulfate solution converts nitrogen containing compounds in the sample into nitrate. UV spectrophotometry is used to measure absorbance A220 and A275 at wavelengths of 220nm and 275nm, respectively. The corrected absorbance A is calculated according to the formula, and the total nitrogen (calculated as N) content is proportional to the corrected absorbance A.
