近年来,医学上发现长期过量地摄入铝,会引起人体细胞和细胞组织的磷酸化,也影响某些酶的活性,从而引起老年性痴呆.虽然近期有一些测定铝的报道[1,2],但由于种种原因,其方法的应用受到一定的限制.我们在文献的基础上,对铝的极谱行为进行了研究,发现在pH2.9的酸性介质中,铝与铬兰 In recent years, medical studies have found that long-term excessive intake of aluminum, can cause phosphorylation of human cells and tissues, but also affect the activity of certain enzymes, which led to Alzheimer’s disease.Although some recent reports of the determination of aluminum [1,2 However, due to various reasons, the application of this method is limited.On the basis of the literature, we studied the polarographic behavior of aluminum and found that in the acidic medium of pH2.9,
