Abstract

The invention provides a detecting device and method for detecting flow injection chemiluminescence water inorganic mercury by inhibiting, aims to solve the problems that in the prior art, analyzing time is long, conditions are rigorous, energy consumption is high, secondary pollution can be produced, concentration of ozone is unstable and lighting efficiency is low and the like. According to the device, hydrophobic transparent material is coated on on the upper portion on the inner face of a dynamic ozone solution balancing pipe close to the face of a ultraviolet tube, and a plurality of reflectors are arranged on the lower portion. By the aid of the scheme, dissolved ozone is precipitated rarely when the ozone solution flows through a dynamic ozone solution balancing chamber, stability of ozone concentration is guaranteed, and lights are reflected to the solution through the prismatic reflectors to improve ozone-dissolving lighting efficiency. 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 emission control in my country. 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. Therefore, it is realistic to quickly detect total mercury in water bodies. significance. [0003] At present, the commonly used analytical methods in the determination of total mercury in water quality in my country include disulfide spectrophotometry, micellar solubilization spectrophotometry, cold ...
