Description
Technical field
The invention belongs to on-line automatic quantitative chemical analysis field, be specifically related to a kind of digestion pool including initiatively paddle wheel.
Background technology
Current online most water quality monitoring surveying instrument, as online ammonia nitrogen quantitative chemical analysis, mostly adopts physioptial spectrophotometric method, and spectrophotometric method is also the common method that chemical analysis is measured, and is also the common method of monitoring water quality on line surveying instrument.The principle of spectrophotometric method uses the langbobier law in physical optics: Lambert-Beer law: when a branch of collimated monochromatic ligth is by uniform non-scatter sample, sample is directly proportional to the concentration of sample and thickness to the absorbance of light, A=ECl.In actual use, langbobier law application is limited, and reason is that sample is very little to the absorbance of light.Be measured as example with the ammonia nitrogen of water, first it employ the dyeing of chemistry, then adopts the method for the spectrophotometry of physics.Usually, the extinction feature of measured liquid water pollutant ammonia nitrogen is unconspicuous, spectrophotometric method cannot be used to measure, therefore measure and first will select the method for chemical staining: because the ammonia in the alkali lye of potassium iodide mercuric iodixde and water can generate light red brown colloidization compound, this compound has strong light absorption at 410-425nm frequency domain, therefore in pollution water sample, add the process of the alkali lye of quantitative potassium iodide mercuric iodixde, be exactly chemical staining.Secondly, use the spectrophotometric method of physics: the light selecting applicable wavelength (absorbing wavelength=410-425nm after ammonia nitrogen dyeing) according to measured object, measured sample is directly proportional to the concentration of sample and thickness to the absorbance of light.Quantitative light intensity, through the Analysing cuvette " thickness is certain " that measured liquid is housed, light intensity weakens because of strong absorption.Again, measure the light intensity after by Analysing cuvette, because the light path of Analysing cuvette is constant, photon absorbing intensity is directly proportional to the concentration of the pollutant load (ammonia nitrogen) of measured liquid, therefore measures light intensity, is just aware of the content of water quality pollutant ammonia nitrogen.As can be seen here, use spectrophotometric method to measure and pollute, cytochemical staining procedure is the step measuring most critical.In cytochemical staining procedure, uniform stirring is again one of key condition.If do not have uniform stirring, so only have the ammonia of part to be colored, measuring also can only the ammonia-nitrogen content of measure portion, certainly inaccurate.Only have the staining solution in digestion pool, namely the ammonia of potassium iodide mercuric iodixde alkali lye in water sample is fully combined, could Measurement accuracy.How to realize uniform stirring in digestion pool, the present inventor has consulted China and foreign countries' Patent document data of on-line measurement, does not find relevant technical scheme, i.e. prior art, does not solve the technical scheme of sample solution and staining solution uniform stirring in digestion pool.The present invention attempts to provide the technical scheme of sample solution and staining solution uniform stirring in digestion pool.
