银量分析测定对于乳剂和胶片都是非常重要的,如何在实验中快速准确测出乳剂和胶片的含银量呢?我们在实践中所采用的测定银量的方法是电位滴定法。电位滴定法对滴定终点的确定方法有三种:绘制E-V曲线法;绘制ΔE/ΔV-V曲线法;以及二级微商法。在实践中我们认为使用绘制E-V曲线法比较简单易行。绘制E Determination of silver for the emulsion and film are very important, how to quickly and accurately test the silver content of the emulsion and film it? In practice we used to determine the amount of silver is potentiometric titration. Potentiometric titration end point determination of the three methods: draw E-V curve method; draw ΔE / ΔV-V curve method; and the second level of the micro-law. In practice, we think it is relatively easy to use the method of drawing E-V curve. Draw E
