1 实验及结果实验时测最吡啶银胶系统中掺入不同浓度KCl溶液时的散射谱。银胶未加样品时呈黄色,与吡啶溶液的体积比为6:1.上述系统中掺入不同浓度的KCl水溶液0.5mL,并在加入KCl5min后,分别测量其散射谱。图1给出了1×10~(-2)M吡啶银胶系统中掺入KCl后的散射谱。曲线A,B,C对应所加KCl浓度分别为0,3×10~(-4)M,6×10~(-4)M。由图可以看出:对比
EXPERIMENTAL RESULTS In the experiment, the scattering spectra of silver pyridine system with different concentrations of KCl were measured. The silver glue was yellow when the sample was not added, and the volume ratio of the silver solution to the pyridine solution was 6: 1. The above system was mixed with 0.5 mL of KCl aqueous solution of different concentrations, and after the addition of KCl for 5 minutes, the scattering spectra were respectively measured. Figure 1 shows the scattering spectra of 1 × 10 ~ (-2) M pyridine silver gel system after the addition of KCl. The concentrations of KCl in the curves A, B and C correspond to 0, 3 × 10 -4 M and 6 × 10 -4 M, respectively. Can be seen from the figure: contrast
