Aluminium

Aluminium
Aluminium occurs naturally in a variety of types of compounds and can be found in acid, neutral and alkaline solutions. It is also found as fine suspended particles in rivers in the form of clays and zeolites but these compounds are not usually considered as aluminium compounds in the context of the water cycle. The determination may be used to check the absence of aluminium in waters treated with aluminium salts as a flocculant.
