METAL COMPLEX, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF IN PREVENTION AND CONTROL OF HEAVY METAL HAZARDS

摘要

The present invention relates to the field of prevention and control of heavy metal hazards, and particularly to a metal complex, a preparation method therefor and application thereof in the prevention and control of heavy metal hazards. The present invention provides a metal complex. The present invention also provides a preparation method for the metal complex. The present invention also provides application of a product obtained from the metal complex or by the preparation method in the field of preparing cadmium scavenger, in the field of removing heavy metal residues in food, agricultural products, and vegetables; and in treating soil and water heavy metal pollution and removing heavy metal residues in aquaculture. The product of the present invention is easily soluble in water, and heavy metal ions can replace the metal ions in the metal complex, thereby deactivating the active heavy metals without being absorbed; in addition, it is obtained from animal experiments that the cadmium removing effect is good and the toxicity is low, so that the technical defect that heavy metal scavengers in the prior art cannot achieve both a good effect on heavy metal removal and low toxicity is solved.
