胆矾结晶水含量的测定方法有很多种,最为常见的是重量法。本实验设计中,改变定量分析的思路,利用硫酸铜溶液的蓝色,通过色度传感器运用吸光光度法分析溶液的浓度,从而测出胆矾中结晶水含量。 There are many ways to determine the cholesteric water content, the most common being the gravimetric method. In this experiment design, the idea of ​​quantitative analysis was changed. Using the blue color of the copper sulfate solution, the concentration of the solution was analyzed by a colorimetric sensor and the crystal water content in the cholesteric fluid was measured.
