Development of biosorbent derived from the endocarp waste of gayo coffee for lead removal in liquid wastewater—effects of chemical activators

This study reports the development of bio-based adsorbent by utilizing coffee endocarp (CE) waste as a raw material for lead (Pb) removal from liquid wastewater. The effect of NaOH and HCl as activation precursors on the characteristics and performance of the resulting adsorbents was investigated. T...
