Abstract:
Objective To establish a method to determine cobalt in human urine by graphite furnace atomic absorption spectrometry.Methods Urine with 2％ nitric acid diluted two-fold,to quantify the curve,graphite furnace atomic absorption spectrometric detection.Results Co was linear within 2.5～40.0 ng/ml with r＞0.999.Spike experiment showed that Co received good recovery rate,which was 90.8％～94.8％.Intra-assay precisions were 3.2％～5.1％ for Co,inter-assay precisions were 4.4％～5.2％ for Co.Conclusion The method by using graphite furnace atomic absorption spectrometr to determine urine Co was fast,accurate and with low matrix effect.It could meet the requirement in GBZ/T 210.5-2008.
