ABSTRACT
OBJECTIVE:
To establish a methodology to dilute blood sample with compound matrix modifier,and to determine the blood level of nickel using improved graphite furnace atomic absorption spectrometry( GFAAS).METHODS:
The blood samples( 100. 00 μL) were diluted 5 times in 0. 12 g / L mass concentration of palladium chloride combined with 1. 00 %(V /V) Triton X-100 and 0. 10%(V /V) nitric acid,and the blood level of nickel was detected by GFAAS.RESULTS:
The good linearity range of nickel mass concentration in blood was 0. 30-25. 00 μg / L,the correlation coefficient was 0. 999 7,the detection limit was 0. 30 μg / L,the minimum detectable mass concentration was 1. 50 μg / L,the recovery rate was99. 00 %-102. 75 %. The within-run and between-run relative standard deviations were 1. 43 %-3. 70 % and 2. 20 %-5. 03 %,respectively. Blood samples can be stored for at least 7 days at 4 ℃.CONCLUSION:
This method is simple for operation,with high accuracy and precision,which is suitable for determination of nickel in blood in normal individuals and workers with occupational exposed to nickel.
