| Abstract: | Hair was prepared as solution by infiltrating in superior grade pure nitric acid, laying aside throughout night and heating in water bath. Furnace atomic absorption spectrometer was used to determine copper in the hair. Under designed standard conditions, the detection limit was 0.005mg/L, analytical precision 2.4% and recovery rate 94.8~105.2%. |
