| Abstract: | A method for the colorimetric determination of traces of zinc in bauxite, alumina, and refined aluminium by means of dithizone is proposed. Ga, Fe, Si, Ti, Ni, Pb, Ca, Mg, Na, etc. do not interfere; Co interferes but can be masked with cyanide. The limit of sensitivity of the method is 2 p.p.m. for bauxite and alumina and 0.4 p.p.m. for aluminium. |
