摘要：

The fluorescence of cobalt atoms in air-hydrogen, air-propane and air-acetylene flames is described. Resonance fluorescence is obtained at 240.73, 242.49 and 252.14 nm with a high-intensity hollow-cathode lamp or a microwave-excited electrodeless discliarge tube as source. Cobalt may be determined by E.D.T. excitation in the range 0.01-7.0 p.p.m. in aqueous solution with a detection limit of 0.005 p.p.m. at the 240.73 nm line. An oxidizing air-propane or air-hydrogen flame is best for atomic fluorescence measurements. © 1969.
