摘要
本文通过锡石Zeta电位的测定和对混合甲苯肿酸在锡石表面上吸附的考察,采用红外光谱、俄歇能谱和光电子能谱进行表面分析,详细地研究了混合甲苯胂酸在锡石表面上的吸附机理,认为混合甲苯胂酸在锡石表面上是以化学吸附为主,并存在静电和分子吸附的多层不均匀吸附。
The adsorption mechanism of mixed toluenearsonic acid on the surfaces of cassiterite minerals is studied by measuring zeta potential of cassiterites and investigating the adsorprtion of mixed toluenearsonie acid on the surfaces of cassiterite minerals as well as by analysing the surficial adsorption layer of cassiterite minerals using infrared spectra, ager energy spectra and photoelectronie energy spectra. It is concluded that the adsorption of mixed toluenearsonae acid on the surfaces of cassiterite minerals dominates is mainly a chemicl adsrption.
