; ;
Research was conducted on the use of some reagents for the spectral determination of solutions of zirconium and hafnium. The behavior of lacquers composed by two cations with phenylfluoron, gallein, R eriocromocianin, thoron, and S alizarin was studied. The best analysis results were obtained by S alizarin. Some considerations were made on results obtained and some possibilities of improvement of the analytic method are discussed. (auth)
