摘要
研究表明,聚丙烯酸钠(PAS)能选择性解吸方铅矿表面吸附的黄药,PAS在方铅矿表面是以化学吸附为主;氢键作用可能同时存在。表面黄药的选择性解吸和PAS的亲水造成了方铅矿的抑制;并提出了吸附模型。
The study shows that in alkaline solution PAS can desorb the adsorbedproduct of lead xanthate on galena surface selectively. It is considered thatPAS is adsorbed on galena mainly through chemical bonding. The action ofhydrogen bonding probably happens on galena. The depression of galena iscaused by the desorption of xanthate and the hydrophilicity of PAS. Theadsorption mode1 of PAS on galena has been proposed.
