摘 要:为解决提取冶金中SO2的污染问题,通过绘制SO2-H2O系的log PSO2/[SO2]T-PH图,阐明了碱液吸收的原理。再制作MeSO3-H2O系的log[Me2+]·α-pH和log[Me2+]·PSO2-pH图,说明了固体氧化物水浆吸收的热力学条件。
Abstract: In order to benefit the resolution of the SO2 pollution problems inextractive metallurgy, at first, we have constructed log-PSO2/[SO2]T pH diagramfor SO2-H2O system, which is used to elucidate the principle of alkalineabsorption. Second, log [Me2+·α-pH and log [Me2+. PSO2- pH diagrams for MeSO3-H2O systems have also been constructed, which can be used toexplain suitable conditions for solid oxide pulp absorption.
