Talanta. 1969 Jul;16(7):915-20. doi: 10.1016/0039-9140(69)80131-1.

Abstract

The polarographic determination of aluminium as its complex with alizarin in the pH range 9.2-10.1, with the cathode ray polarograph, is described. A solvent extraction procedure is used to eliminate interferences from many other metals.
