dc.description.abstract用极化曲线法研究了0.5mol·L-1硫酸溶液中β-苯胺基苯丙酮(PAP)在铁-溶液界面的吸脱附行为及Cl-,I-的影响.结果表明,PAP的吸附遵循Flory-Huggns等温式;在较正的极化电位区出现阳极脱附现象.讨论了两种粒子联合吸附方式与浓度的关系,提出可根据吸附粒子的脱附电位与其浓度关系来推断联合吸附的理论模型zh_CN
dc.description.abstractThe adsorption desorption behaviors of β phenylaminopropiophenone (PAP) on iron in 0.5 mol·L -1 H 2SO 4 solution with or without halide ions (Cl -,I -) were investigated by potentiostatic polarization measurement. The results show that the adsorption of PAP on iron surface follows Flory Huggins isotherm, the adsorption free energy parameter ( f ) is positive in H 2SO 4 solution; In the presence of 0.1 mol·L -1 Cl -1 , when C PAP ≤2×10 -5 mol·L -1 , f0 . A desorption phenomenon was observed at more positive potential region in anodic polarization curves. Furthermore, the anodic desorption potential ( E des ) of PAP+X - is independent of PAP concentration at lower concentration region, and E des vs. lg C PAP is a straight line at higher concentration region. The joint adsorption modes under different conditions were determined according to the above stated relation of E des to PAP concentrations as well as the adsorption free energy parameter f values.zh_CN
