摘要
研究了部分水解聚丙烯酰胺（HPAM）在石英砂表面的吸附量与HPAM浓度的关系．结果表明，HPAM在石英砂上的吸附基本符合Langmuir吸附模式，并且是不完全可逆吸附．XPS分析表明，N／Si原子比基本反映了HPAM在石英砂表面上的吸附量，N1结合能的升高反映了HPAM和石英砂表面间的氢键作用．
The relationship between the concentration of partially hydrolyzed polyacrylamide(HPAM) and the quantity of HPAM adsorbed on the SiO2 surface was studied. The X-rayphotoelectron spectroscopy(XPS) was used to investigate the interaction between the poly-mer molecules and the adsorbent surface. The experimental results show that the adsorptionof HPAM on SiO2 surface is consistent with Langmuir model. XPS analysis of the samplessurface shows that the N/Si atomic concentration ratio reflects the quantity of HPAM ad-sorbed on the SiO2 surface, and the increase of N15, binding energy is related to the formationof the hydrogen-bonding between the HPAM molecules and the SiO2 surface.
