近几年来,国内外对铝的生理毒性日益重视,已发现铝对肾脏病患者是一种毒剂。铝在人体中积累,就会损害大脑和骨骼,导致老年性痴呆和骨质病变等。由于铝在环境中无处不在,有关铝及其生理作用的研究已成为近十几年来重要的研究课题。这些研究都迫切需要一种能准确测定微(痕)量级铝的分析方法。微(痕)量级铝的测定,过去采用铬天菁S比色法。其他仪器分析方法,如中子活化分析和火焰原子吸收光谱法,因不适用于绝
In recent years, the domestic and international attention to the physiological toxicity of aluminum, aluminum has been found in patients with kidney disease is a poison. Aluminum accumulation in the human body, it will damage the brain and bones, leading to Alzheimer’s disease and bone disease. Due to the ubiquity of aluminum in the environment, the research on aluminum and its physiological functions has become an important research topic in recent ten years. All these studies urgently need an analytical method that can accurately measure micro (trace) levels of aluminum. Micro (marks) the determination of the level of aluminum, the past using chrome cyanine S colorimetric method. Other instrumental analysis methods, such as neutron activation analysis and flame atomic absorption spectrometry, are not suitable
