本文研究了27Al在强酸强碱体系中的化学位移,利用核磁共振技术建立了一个适合复杂体系中无干扰测定铝的新方法。研究了共存离子及不同实验参数对分析结果的影响。结果表明该方法特别适合于含铝混合物、铝合金及矿物等复杂体系中铝的定性定量分析。相对平均偏差0.18%,相对标准偏差0.54%。
In this paper, the chemical shift of 27Al in strong acid and alkali system was studied. A new method for nondestructive determination of aluminum in complex system was established by using nuclear magnetic resonance technique. The effects of coexisting ions and different experimental parameters on the analytical results were studied. The results show that this method is particularly suitable for qualitative and quantitative analysis of aluminum in complex systems containing aluminum compounds, aluminum alloys and minerals. The relative average deviation of 0.18%, the relative standard deviation of 0.54%.
