Description

technical field [0001] The invention belongs to the technical field of water quality analysis, in particular to a device and method for on-line analysis of heavy metals in water. Background technique [0002] Water quality monitoring is an important part of environmental monitoring. It can accurately and timely reflect the current situation and development trend of water quality, provide scientific basis for water environment management, pollution control and environmental planning, and play a role in water resource protection, pollution early warning and control, and maintenance of water quality health. importance and significance. Heavy metal elements cannot be biodegraded, but can exponentially grow and enrich in organisms along the food chain, and finally enter the human body. Heavy metals can strongly interact with proteins and various enzymes in the human body, causing them to lose their activity, or accumulate in some viscera and organs of the human body, causing hea...
