Abstract

The invention provides a detecting device and method for detecting flow injection chemiluminescence water inorganic mercury, aims to solve the problems that in the prior art, an ozone solution is easy to decompose, on-site operation cannot be performed, analyzing time is long, analyzing process is complicated, conditions are rigorous, energy consumption is high, secondary pollution can be produced and the like. A catalyst of ruthenium trichloride is filled into a dynamic ozone solution balancing pipe; when the ozone solution flows into the dynamic ozone solution balancing pipe, the catalyst of the ruthenium trichloride is irradiated by a fluorescent light, the ozone in the ozone solution is inhibited from generating hydroxyl radicals, the ozone solution is stable and decompose rarely, and stability of the ozone solution is improved. The detecting device used for detecting the inorganic mercury in water has the advantages of scene, rapidness, convenience and flexibility.

Description

technical field

[0001] The invention relates to the technical field of environmental chemical monitoring, in particular to a detection device and method for measuring heavy metals in water. Background technique

[0002] Mercury is a poisonous metal. Once mercury poisoning occurs, it will cause great damage to the human body. Mercury in water mainly comes from geological and environmental pollution. Mercury is one of the indicators for total discharge control in my country, and it is a must-test item for environmental protection and water quality inspection of urban water supply and drainage systems. my country has strict regulations on mercury content in environmental water bodies, so rapid detection of inorganic mercury in water bodies is realistic. significance.

[0003] Years of monitoring results show that the content of inorganic mercury in water is low, which belongs to trace level. If direct measurement requires water sample enrichment process, so in order to obtain ...
