Description
Technical field
The utility model relates to a kind of water quality monitor, relates in particular to a kind of Automatic On-line ammonia Nitrogen Analyzer.
Background technology
Mensuration for Water quality ammonia nitrogen: ammonia nitrogen (NH3-N) is present in water with free ammonia (NH3) or ammonium salt (NH4+) form, and both ratio of componentss depend on pH value and the water temperature of water.When pH value is higher, the ratio of free ammonia is higher.Otherwise the ratio of ammonium salt is high, water temperature is contrary.
The assay method of ammonia nitrogen mainly contains Na's colorimetry, gas molecule in space absorption process, phenol---hypochlorite (or salicylic acid---hypochlorite) colourimetry and electrode method etc.This section is by article Na's colorimetry and distillation---acidimetry.When water sample band look or muddy and contain some other interfering material, affect the mensuration of ammonia nitrogen.For this reason, when analyzing, need do suitable pre-service.To more clean water, can adopt flocculent precipitation (add appropriate zinc sulfate in water sample, and hydro-oxidation sodium makes alkalize, generate zinc hydroxide precipitation, then remove after filtration color and muddiness); To with serious pollution water or industrial waste water, by the way of distillation, eliminate to disturb (regulating the pH value of water sample to make the scope at 6.0-7.4, adding appropriate magnesium oxide to make into alkalescence, distilling the ammonia discharging and be absorbed in sulfuric acid or BAS.While adopting Na's colorimetry or acidimetry, take BAS as absorption liquid; Adopt salicylic acid---during hypochlorite colourimetry, take sulfuric acid solution as absorption liquid).And in prior art for the complex structure of the top blast absorption plant of Water quality ammonia nitrogen monitor, use inconvenient, make operating process loaded down with trivial details, inefficiency, and monitoring velocity is slow, stability is not high, therefore, has larger room for improvement.
