EM-EDX characterization of OFI materials Further insight on the nature of the OFI powder and mucilage together with elementary composition were gained through the use of the Scanning Electron Microscopy coupled with energy dispersive X-ray analysis (EDX). The techniques established the morphology, porosity, texture and the elementary compositions with their relative percentages on the surface of the material.Fig. 2 shows the SEM images of activated fibre Biochar, Cactus leaf fibres and Cactus cladode fibres that were used in pollutant removal.Fig. 2(a) shows that the activated fibre Biochar consisted of lamellar structures that gave strength, toughness and large surface area to the material while the micro channels allowed for rapid movement off luids through the fibres giving them the chance to
