The conventional ammonia nitrogen analyzer mainly uses an ion selective electrode method, which is composed of a potassium ion selective electrode, a pH electrode (reference electrode) and a temperature electrode to form an integrated electrode, which comprises a sensor electrode film head and a sensor electrode film. The head generates an electrochemical reaction, and the electrochemical reaction is converted by the concentration of the ammonia ion to obtain the ammonia nitrogen content in the sewage water. However, the biggest disadvantage of the ion-selective electrode method is that the sensor electrode tip should be replaced frequently, and the sensor electrode tip will age or block the passivation, so it takes about 10-14 days to calibrate once, which causes labor expense, and the sensor The electrode tip will be offset and will be replaced in about 2-3 months, which is not economical.

Another conventional ammonia nitrogen analyzer is a salicylic acid spectrophotometric method or a Nessler reagent colorimetric method. The salicylic acid spectrophotometric method is based on a sodium salicylate colorimetric method for measuring ammonia nitrogen content in water, in an alkaline medium. Under the condition of catalyst, ammonia nitrogen reacts with salicylate in the form of free ammonia or ammonium ions to form a colored complex. The analyzer converts the ammonia to the ammonia concentration according to the color depth of the complex. value. The principle of the Nessler reagent colorimetric method is to react with ammonia nitrogen or ammonium ions in the presence of free ammonia or ammonium ions to form a reddish brown complex. The absorbance of the complex is proportional to the ammonia nitrogen content, and the complex is The characteristic absorbance is measured at the absorption wavelength, and the ammonia nitrogen content in the water sample is calculated by the meter.

The conventional total phosphorus analyzer measures the total phosphorus content in water based on the colorimetric method. The principle is that polyphosphate and other phosphorus-containing compounds in water are hydrolyzed under high temperature or high pressure acidic conditions to form phosphate, and other difficult-to-oxidize phosphorus compounds. , by the strong oxidant sodium persulfate oxidation to phosphate. Phosphate in a strong acid solution containing molybdenum ionic acid salt, a bismuth compound is produced, which is reduced to ascorbic acid by the ascorbic acid, and the absorbance of the phosphomolybdate is measured, and the water is obtained in comparison with the standard. The total phosphorus content in the sample is used.

Another method for measuring the total phosphorus content in water is potassium persulfate or nitric acid-perchloric acid to digest the sample and convert the total phosphorus content to orthophosphate. In an acidic medium, orthophosphate reacts with ammonium molybdate to form a molybdenum heteropolyacid in the presence of a cerium salt, which is immediately reduced by the anti-exchangeable acid to form a blue complex. The absorbance is proportional to the total phosphorus concentration. .

The conventional total nitrogen analyzer is based on the colorimetric method for measuring the total nitrogen content in water. The principle is that the alkaline potassium persulfate solution converts the nitrogen of the nitrogen-containing compound in the sample into nitrate at 120-124 ° C. The absorbance was measured by ultraviolet spectrophotometry at wavelengths of 200 nm and 275 nm, and the corrected absorbance was calculated according to the formula. The total nitrogen content was corrected to the corrected absorbance to obtain the total nitrogen content in the water.

However, the above-mentioned methods for measuring the content of ammonia nitrogen or total phosphorus or total nitrogen in water are mainly measured by administration, and in addition to the expensive cost of the analytical instrument itself, the cost of the drug itself is also quite high, and it causes secondary pollution, and Regardless of the electrode method or the drug administration method, the equipment and special drug consumables and manual maintenance costs are quite high, and the analysis time is about 30 minutes to 1 hour, which cannot achieve the purpose of immediate monitoring and control, and does not meet the environmental and economic costs.
