| 摘 要： | 研究了水解的聚丙烯酰胺(HPAM)在海泡石上的吸附及水解度, pH值和离子强度对吸附的影响, HPAM在海泡石上的吸附等温曲线发现属Langmuir型. 吸附能为-17到-20kJ/mol. 吸附量随HPAM水解度和pH的增长而减少, 随盐的浓度增大而增大.

| Abstract: | Adsorption isotherms of hydrolyzed polyacrylamide (I) on sepiolite were Langmuir type and the energy of adsorption was -17 to -20 kJ/mol. The amount of adsorption decreased with increasing degree of hydrolysis of I and pH, but increased in the presence of NaCl. The results were discussed in terms of changes in configuration of I, surface properties of sepiolite, and interaction between I and sepiolite. |
