This paper presents a method for the determination of trace amounts of zirconium and hafnium in soil and rock by ICP-AES after simple separation and enrichment. The detection limits were 0.033 and 0.012ppm respectively. First, the instrument and working conditions JY-70P plasma light meter, glass atomizer, do not dissolve, double mist chamber and the combination of torch. The cooling gas was 15 liters / minute, the plasma gas was 0.4 liters / minute and the carrier gas was 0.3 liters / minute (3 kg / cm 2). Cleaning time 15 seconds, plot
