[0023] This embodiment takes the determination of total nitrogen as an example:

[0024] Rationale: The alkaline persulfate digestion process converts all forms of nitrogen into nitrates. After the digestion, a masking agent was added to remove the halogen oxidizing substances. Then the nitrate reacts with the chromotropic acid in a strongly acidic environment to form a yellow complex. According...

Abstract

The present invention discloses a water quality analyzer which comprises a processor, the processor is respectively connected with and controls a submersible pump, a peristaltic pump, a heating wire, a cooler and a luminescent tube, one end of the submersible pump is communicated with a water inlet, the other end of the submersible pump is communicated with a sampler, and the sampler is communicated with a nine-way valve. The nine-way valve is respectively communicated with more than one standard bottle, more than one reagent bottle, a quantitative tube, a waste liquid bottle and a digestion colorimetric pool, an outlet end of the digestion colorimetric pool is communicated with a waste gas collector, a heating wire, a cooler and a luminous tube are all arranged at the digestion colorimetric pool, and a first high-pressure electromagnetic valve and a second high-pressure electromagnetic valve are respectively arranged at two ends of the digestion colorimetric pool. An infrared liquid level sensor is arranged in the quantitative tube, the infrared liquid level sensor is electrically connected to the processor, and the peristaltic pump is arranged between the digestion colorimetric pool and the quantitative tube.

Description

technical field [0001] The invention relates to the field of environmental protection monitoring, in particular to a water quality analyzer. Background technique [0002] Drinking water mainly considers the impact on human health, and its water quality standards include not only physical and chemical indicators, but also microbial indicators; for industrial water, it is considered whether it will affect product quality or easily damage containers and pipelines. It can be widely used in various ions in power plants, pure water plants, tap water plants, domestic sewage treatment plants, beverage plants, environmental protection departments, industrial water, aquaculture, textile industry, wine making industry and pharmaceutical industry, epidemic prevention departments, hospitals and other departments Parameter determination. Water quality analyzers are used to detect water quality. The current water quality analyzers on the market have single functions, low degree of automat...
