【Abstract】 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.更多还原
