To sum up:
Benefits:
When drinking water from a silver cup, positively charged silver ions can be separated. Silver ion has bactericidal effect because it can adsorb bacteria and inactivate them. Silver ions have bactericidal effect, which is supported by experiments, and the principle is still controversial.
In addition, silver also has the functions of accelerating wound healing, preventing infection, purifying water quality, keeping fresh and preserving corrosion. Storing food with silver tableware can prevent the growth of bacteria and prolong the shelf life of food.
Danger:
The low concentration of silver ion (below 15 μg/L) shows signs of promoting microbial reproduction.
Pure silver has no obvious physiological effect on human body, but its mechanical strength is too poor. Silver alloy usually contains copper and nickel, which is irritating to the digestive tract.
