摘要
In this paper,the adsorption characteristics of sodium tetraphenylborate（NaBPh4）on activated carbon at 298.2,303.2,308.2,313.2 and 323.2 K was studied.The results show that the adsorption isotherm of NaBPh4 on activated carbon at different temperatures could be described using Langmuir equation.Furthermore,the standard Gibbs energy,enthalpy,entropy and hydrophobic interaction Gibbs energy for the adsorption of NaBPh4 on activated carbon were studied,and the result shows that the hydrophobic interaction of BPh-4 ion plays the most important role for the transfer of NaBPh4 from water to activated carbon surface.
