三硫代碳酸盐(TTC)在基质表面上的吸附与基质表面的电位有关。在本工作中证实了TTC起到了硫醇或硫醇盐在表面上吸附的中间物的作用。而二硫代碳酸盐(黄药)仅在有阳极电流存在时才在表面上吸附。但在有阳极电流存在时TTC的吸附速率增大。由此可知,硫醇盐在黄铁矿和铜表面上的吸附量不大。TTC只对硫醇或硫醇盐在基质表面上吸附起到促进作用。
The adsorption of trithiocarbonate (TTC) on the substrate surface is related to the potential of the substrate surface. In this work, it was confirmed that TTC functions as an intermediate adsorbed on the surface of mercaptan or thiolate. Dithiocarbonates (xanthate) adsorb on the surface only when anodic current is present. However, the adsorption rate of TTC increases in the presence of anodic current. It can be seen that the adsorption amount of thiolate on pyrite and copper surface is not large. TTC promotes the adsorption of thiols or thiolates on the substrate surface only.
