探讨不同离子浓度与不同无机溶液的混合对紫外光吸收的影响，结果表明，盐酸盐在较高浓度下吸收值迅速增大,吸收峰向红区移动,而硫酸盐在远紫区有一定程度的吸收，KH2PO4与NH4F接近无吸收。多数情况下，无机溶液对紫外光的吸收主要决定于阴离子类型，而与阳离子无关.不同类型溶液的混合基本不改变溶液的吸收特性，硝酸盐在低浓度下对紫外的吸收极为稳定，基本不受共存离子的干扰。0.01mol/LCuSO4与2mol/LKCI吸收峰与硝酸盐吸收峰重叠，但饱和CaSO4与硝酸盐吸收峰不重叠。
The effects of different ion concentration and different inorganic solutions on the UV absorption were investigated. The results showed that the absorption of HCl rapidly increased at higher concentration, and the absorption peak moved to the red zone. The degree of absorption, KH2PO4 and NH4F almost no absorption. In most cases, the absorption of UV light in inorganic solution is mainly determined by the type of anion but not with cation. The mixing of different types of solution basically does not change the absorption characteristics of the solution. The absorption of UV at a low concentration of nitrate is very stable, By the coexistence of ion interference. 0.01mol / LCuSO4 and 2mol / LKCI absorption peak overlap with the nitrate absorption peak, but the saturated CaSO4 and nitrate absorption peaks do not overlap.
