washing are omitted. Cr and Fe do not greatly interfere even when actually present during the test, as 0.1 mg. of Al can readily be detected with 3 mg. of Fe or 5 mg. of Cr. The ether-purpurin test has given satisfactory results as a qualitative reagent for class use over a period of two years and offers a considerable saving of time over other methods of testing for aluminum.
