摘    要:研究了部分水解聚丙烯烯酰胺(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,N1s结合能的升高反映了HPAM和石英砂表面间的氢键作用。

关 键 词:水解 聚丙烯酰胺 石英砂 静态吸附 XPS 吸附

Abstract: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.
Keywords:HPAM   XPS   SiO_2   Static adsorption
