研究了石墨炉原子吸收法测定全血中锰和铝的方法。并提出测锰采用含硝酸镁和氨水为基体改进剂 ,测铝采用含硝酸铜和氨水为基体改进剂。按 1∶ 5体积比稀释血样 ,建立无干扰的加入法基体匹配校准曲线。本法检出限低 ,灵敏度高 ,实测样品具有良好的准确度和精密度。 The method of graphite furnace atomic absorption spectrometry for the determination of manganese and aluminum in whole blood was studied. And proposed measuring manganese using magnesium nitrate and ammonia as a matrix modifier, measuring aluminum containing copper nitrate and ammonia as a matrix modifier. Blood samples were diluted 1: 5 by volume to establish a matrix-matched calibration curve without interference. The law detection limit low, high sensitivity, the measured sample has a good accuracy and precision.
