General description

Aluminum sulfate is one of the components of Nuclear Fast Red solution.It is a coagulant used for arsenate removal from water.

Application

Aluminum sulfate has been used in the preparation of the nuclear-fast red solution for red nuclear counterstaining in histology and cytology protocols. It may be used as a catalyst for the conversion of lactic acid to acetaldehyde via decarbonylation.
Aluminum sulfate may be used to form a porous composite adsorbent with graphene hydrogel to be used for fluoride removal from water.
