Is it good to drink water from an aluminum kettle?

First of all, aluminum is a very active metal, so we use aluminum products, the most surface layer is not aluminum, but a thick layer of aluminum oxide, and aluminum oxide in the neutral, weakly acidic (weakly alkaline) conditions are very stable, for example, ruby, sapphire, the main component of alumina, the composition of the soil alumina is also accounted for the majority of the composition of the water, we usually drink the tap water are neutral acidic, will not make the aluminum ions released. The aluminum ions in the alumina will not be released.

Secondly, we know that the aluminum ion is a kind of metal ion that is very easy to hydrolyze. Heating, dissolved carbon dioxide in the water can make aluminum ions produce aluminum hydroxide precipitation, so even if there are aluminum ions, it is difficult to exist in large quantities in the water.

Once again, aluminum is one of the highest content of elements in the earth's crust, there is a large amount of aluminum in nature, so there is no need to talk about aluminum, as long as the normal use of aluminum products, do not use it for a long time to hold the acidic or alkaline liquids, these aluminum products are very safe, and they seeped out of a very small amount of aluminum ions will not be harmful to the human body.
