PtNi nano-alloys loaded ordered mesoporous carbon for use in clofibric acid adsorption

In this study, PtNi nano-alloys embedded in highly ordered mesoporous carbons have been prepared via an impregnation approach. The PtNi/OMC was characterized by BET surface area, TEM, XPS and XRD (low and wide angle) analysis. The adsorption of clofibric acid on PtNi/OMC with different variable such...

Description
Summary:In this study, PtNi nano-alloys embedded in highly ordered mesoporous carbons have been prepared via an impregnation approach. The PtNi/OMC was characterized by BET surface area, TEM, XPS and XRD (low and wide angle) analysis. The adsorption of clofibric acid on PtNi/OMC with different variable such as: contact time, adsorbent dosage, initial concentration, pH, and temperature was investigated. The kinetic studies showed that the adsorption data followed a pseudo second-order kinetic model. The isotherm analysis indicated that the adsorption data can be represented by Langmuir isotherm model.
