Low-cost adsorbents for cleaning contaminated waters

Characterisation of rice husks with TESCAN SEM VEGA3 XMU
This work evaluates the removal of a cationic dye from simulated waste water onto rice husks. The study has revealed that rice husks have a great potential to sequester cationic dyes from aqueous solutions and therefore it can be utilised to clean contaminated effluents. The surface morphology of the rice husks was characterized by means of scanning electron microscopy (SEM) using the TESCAN SEM VEGA3 XMU coupled with energy dispersive X-ray spectrometer for elemental analysis.
