用铝盐涂覆石墨管并以K2Cr2O7和TritonX-100为基体改进剂。GFAAS法测定骨肿瘤患者血清中微量铝,大幅度提高测定灵敏度和准确度。避免了沾行。特征浓度则.15pg／0.0044A·S。加标平均回收率104.92％,RSD＜8.17％。
Graphite tubes were coated with aluminum salt and K2Cr2O7 and TritonX-100 as matrix modifiers. GFAAS method for the determination of trace amounts of serum aluminum in patients with bone tumors, significantly improve the determination of sensitivity and accuracy. Avoid dip. The characteristic concentration is then 15 pg / 0.0044 A · S. The average recovery rate of 104.92%, RSD <8.17%.
