| Abstract: | Objective:To testify veracity and precision for improved determination method of pb in whole blood sample with detection of quality control sample.Methods:Acidified by adding 10% nitric acid,after centrifugalization and separation the blood sample was injected with matrix modifiers together,using graphite furnance to atomize sample and zeeman effect to correct the disturbance of background,getting the area of pb absorption,the result of whole blood pb was found in calibration curve,analysing quality contral sample while measuring the pb level of the whole blood sample.Results:The results were satisfied by using improved preparing steps to determine quality control sample.Conclusion:The improved measuring conditions for detection of blood pb are reasonable. |
