Abstract
Biochar derived from agro industrial waste has been considered as promising green adsorbent due to its significant availability and affordable production This study investigated and evaluated the adsorption performance of biochar from exhausted coffee husk (ECH). The influence of carbonization process parameter, namely temperature (300, 400, 500, 600°C), residence time (30, 60 and 120 minutes), and rate (5, 10, 15°C/min) on the removal of copper (II) ion (Cu2+) at different biochar dosages (0.2, 4, 0.6, 0.8, 1 g) were investigated. The increasing of carbonization temperature, residence time, rate and biochar dosage showed different adsorption characterization on Cu2+ The carbonization temperature of 600°C resulted in highest removal efficiency of 92%. Furthermore, surface analyzer Brunauer-Emmett-Teller (BET) was used to characterize the adsorbent while and Scanning Electron Microscope (SEM) was used to observe the surface morphology of biochar at the different carbonization The results showed that the carbonization temperature affected the surface area of the ECH
