Change or block passivation, so probably to calibrate within 10-14 days or so once, causes manually consuming very big, and the sensor electrode
Film head can deviate, and will replace within about 2-3 months, and not meet economic benefit.
Nh 3-n analyser is using salicylic acid spectrophotometry or reagent colorimetric method, the bigcatkin willow in another existing water
Sour spectrophotometry is based on the ammonia-nitrogen content in Alysine (Marion Merrell Dow) colorimetric method measurement water, in the condition of alkaline medium and catalyst
Under, there are ammonia nitrogens in the form of the ammonia of free state or ammonium ion etc. reacts with salicylate and generates a kind of colored complex compound, analyzes
Instrument is finally converted according to complex compound shade degree and turns to ammonia nitrogen concentration value.And the principle of the reagent colorimetric method
It is that there are ammonia nitrogens with nessler reagent reacts and generate light red brown complex compound, the extinction of the complex compound with the ammonia of free state or ammonium ion
Degree is directly proportional to the content of ammonia nitrogen, and absorbance is measured at the characteristic absorption wavelength of the complex compound, water is calculated by instrument
The content of ammonia nitrogen in sample.
For existing total phosphorus analyzer based on the total phosphorus content in colorimetric method measurement water, principle is that Quadrafos contains with other in water
Phosphorus compound generates phosphate radical, for other dysoxidizable phosphorus compounds, then in high temperature or the hydrolyzed under acidic conditions of high pressure
It is received by strong oxidizer persulfuric acid and is oxidized to phosphate radical.Phosphate radical generates a kind of antimony in the strong acid solution of the hydrochlorate containing molybdenum ion
Object is closed, this antimonial is reduced to the phosphomolybdate of blue by ascorbic acid, measures the absorbance and standard phase of phosphomolybdate
Than just obtaining total phosphorus content in water sample and using.
The measurement method of total phosphorus content makes sample digestion for potassium peroxydisulfate or nitric acid-perchloric acid in another water, and will be total
It is phosphorous to be completely converted into orthophosphates.In acid medium, orthophosphates and ammonium molybdate reaction generate phosphorus molybdenum in the presence of antimonic salt
It after heteropoly acid, is restored immediately by anti-change-blood acid, generation blue complex, the concentration of absorbance and total phosphorus is at original.
In existing water total blood urea/nitrogen analyzer be based on colorimetric method measurement water in total nitrogen content, principle be under 120 ~ 124 °C,
Alkaline chitinase solution makes the nitrogen of the nitrogenous compound in sample be converted into nitrate, using ultraviolet spectrophotometry in wavelength
At 200nm and 275nm, absorbance is measured respectively, correction absorbance is calculated by formula, total nitrogen content and correction absorbance are at just
This, to obtain the content of total nitrogen in water.
However, the measurement method of ammonia nitrogen or total phosphorus or total nitrogen content in above-mentioned either water, is surveyed with offeing medicine
Amount method, other than analysis instrument itself involves great expense, drug cost itself is also quite high, and will cause secondary pollution, and
And either electrode method or medication, instrument and equipment and special drug consumptive material and artificial maintenance cost are quite high, and analysis time
About 30 minutes ~ 1 hour or so, it is unable to reach the purpose of real-time monitoring and control, does not meet environment and economic cost in fact.
Therefore, if a kind of full spectroscopic analysis system can be designed, whole spectral regions is obtained, are calculated with artificial intelligence model
Method, the parallel comparison of big data, self deep learning analysed for relevance and various interference factors, calculate amendment weighting parameters
Make mutual numerical compensation and noise filtering (such as turbidity and coloration), to from which further follow that the ammonia nitrogen of more high accurancy and precision, total phosphorus, total
Nitrogen, UV254, COD (COD), total organic carbon (TOC), BOD (BOD), dissolved organic carbon (DOC), Gao Meng
Hydrochlorate index (CODMn), nitrate nitrogen, nitrite nitrogen, coloration, turbidity, total suspended solid, phenol (BTX), ozone or hydrogen sulfide etc. are a variety of
Organic substance concentration should be a best solution.
