The static adsorption of different concentrations of amphiphilic polymer on rocks and minerals is studied by starch-cadmium iodide colorimetric method and the influence of adsorption rules by salinity, temperature and surfactant are discussed. The results showed that the adsorption isotherm of the amphiphi-lic polymer are combined by L style, and H style, having a maximum adsorption peak and showing the characteristics of multilayer adsorption. For different rocks and minerals,the adsorption of amphiphilic pol-ymer on clay (Γmax =11.5 mg/g) is higher than kaolin (Γmax = 10 mg/g) and silica sand (Γmax= 0. 28 mg/g) ;the amount of adsorption of the amphiphilic polymer first decreases slightly and then increa-ses with salinity increasing, and increases with temperature increasing; and surfactant can lead to the de-crease of the original adsorption of amphiphilic polymer.%利用淀粉-碘化镉比色法测定了不同浓度两亲聚合物AP在岩石矿物上的静态吸附量,探讨了矿化度、温度和表面活性剂对其吸附的影响.结果表明,两亲聚合物的吸附等温线由L型和H型构成,存在一个最高吸附峰,具有多层吸附的特征；对于不同岩石矿物,两亲聚合物吸附量大小次序为粘土(Γmax为11.5 mg/g)＞高岭土(Γmax为10 mg/g)＞石英砂(Γmax为0.28 mg/g)；两亲聚合物的吸附量随矿化度的增加先略微降低后又增大,随温度的升高增加；表面活性剂可降低两亲聚合物的吸附量.
