摘要
利用核磁共振技术,测量了不同浓度的FeCl3.6H2O,CuSO4.5H2O和MnCl2.4H2O水溶液的核磁共振信号及横向弛豫时间.实验结果表明横向弛豫时间T2与顺磁离子浓度成反比关系,并由实验结果获得了通过核磁共振横向弛豫时间测量离子浓度的方法.
The nuclear magnetic resonance (NMR) signal and transverse relaxation time of different concentrations of FeCl3.6H2O,CuSO4.5H2O and MnCl2.4H2O aqueous solutions were measured. The experimental results showed that the transverse relaxation time T2 was inversely proportional to the concentration of paramagnetic ions. Based on the experimental results, a method for measuring paramagnetic ion concentration using transverse relaxation time was suggested.
