Description
Technical field
The present invention relates to heavy metal analysis technical field, specifically a kind of biomass cellulose base Cu2+Detect the system of material
Preparation Method and application.
Background technique
Heavy metal pollution problem is always that water environment handles in the middle urgent problem to be solved the most.With economic society
It continues to develop, it is commonplace in recent years about the report of heavy metal pollution problem.Moreover, in industrial wastewater
Heavy metal ion, can not be biodegradable, be easy be enriched in human body, so as to cause damage human organ, lead to serious disease
Become.In existing heavy metal ion, Cu2+With very strong harmfulness, into the intracorporal Cu of people2+It can cause internal organs water
The symptoms such as swollen, causing death when serious.Without effective toxin expelling mechanism in human body, so once taking in Cu2+Just mainly in bone
It is accumulated with liver, and Cu2+It is poisoned no effective antidote, therefore its harm can not be ignored.
In view of Cu2+To the significant damage of human body, how to take effective detection means to Cu2+Carrying out detection is current head
