In this study, charred�desiccated coconut waste was treated with several chemicals, such as NaOH, NaOCl, H2O2, and HNO3, to prepare chemically modified adsorbents. Fourier transform infrared spectroscopy revealed that chemical modification enhanced the surface chemistry of the adsorbent by introdu...
