摘要 对聚乙烯亚胺(PEI)改性硅藻土吸附水溶液中染料活性黑K-BR吸附热力学规律进行研究。结果表明:吸附过程中吸附焓变ΔH>0,为吸热反应;吸附Gibbs自由能变ΔG<0,因而能自发进行;吸附熵变ΔS为正值。 The properties thermodynamics of reactive black K- BR on PEI -modified diatomit (PEMD)in aqueous solution was studied. The results show that The positive values of the adsorption enthalpy ΔH indicates the exothermie reaction. The negative adsorption Gibbs free energy changes ΔG indicates adsorption being spontaneous, adsorption entropy change is positive.
