Abstract

Activated carbon prepared from Caesalpinia pulcherrima pod (CPP) by chemical process shows an excellent improvement in the surface characteristics. Surface morphology plays a very important role in the adsorption properties along with surface functional groups. For the characterization of the activated carbons SEM, FTIR and XRD analyses were performed. The surface morphology porosity of activated carbon (activated carbon from Caesalpinia pulcherrima pod) was visualized via scanning electron microscopy (SEM) analysis. Surface functional groups were detected by Fourier transformation infrared (FTIR) spectroscopy techniques. The results of this investigation indicate that the activated carbon prepared by using Caesalpinia pulcherrima pod (CPP) is a low cost, ecofriendly adsorbent , is expected to be environmentally and economically feasible.
