| Abstract: | A procedure for the direct determination of zinc, cadmium and copper in air and water has been developed. The possible interference effects of numerous anions and cations have been investigated. Few interferences were found, and these were eliminated by the addition of EDTA. The sensitivities found were 2 p.p.b. for cadmium, 8 p.p.b. for copper and 2 p.p.b. for zinc. |
