| 摘 要： | 本研究的目的是为了发展一种在线测定的探测器,测定工业生产中常见的二氧化硫的浓度.首先研究了Ag_2So_4-Li_2So_4体系。在高达10％的二氧化硫浓度下,该体系的电导率仍与浓度无关.电导率与相图的对应关系很好.在氧存在的条件下可用这种电解质测定含量在10％以下的二氧化硫或三氧化硫·用于硫酸铜的分解研究其所得结果与文献中其他方法比较,相差在3％以内.

| Abstract: | The goal of this study is to develop an on-line detector for the measurement of SO_2 in industrial processes. At first the Ag_2SO_4-Li_2SO_4 system was studied. Up to 10% of SO_2 the electric conductivity of the system is still independent of the con- centration of SO_2 and there is a good correspondence between the electric conductivity and the phase diagram of the syetem. The sulfate electrolyte may be used for the concentration measurements of SO_2 or SO_3 if their concentration is less than 10% and with enongh oxygen in existence. The decomposition of copper sulfate was also studied with the electrolytes, compared with reference data, the differences are within |
