电石渣溶解过程中OH^-的溶出研究

Study on Dissolution of OH^- During Dissolution Process of Carbide Slag

电石渣是电石水解获取乙炔后产生的一种工业废渣,主要成分是氢氧化钙,为了电石渣的合理回用并减少其对环境的污染,从溶出温度、搅拌速度、搅拌时间等因素研究了电石渣中OH^-的溶出情况,进而得出电石渣中OH^-溶出的最佳条件,为有效利用电石渣中氢氧化钙成分提供依据。

The carbide slag is a kind of industrial waste by the hydrolysis of calcium carbide to obtain a-cetylene gas. Its main component is calcium hydroxide. For the rational reuse of carbide slag and reduce environmental pollution, the dissolution of OH^- in carbide slag is studied from different dissolution tem-perature, stirring speed and stirring time. The optimal conditions of OH^- dissolution in carbide slag are obtained. It is to provide the basis for the effective use of calcium hydroxide in carbide slag.
