| Summary: | Phenol contamination in wastewater from untreated industrial effluent
poses significant risks to both the ecosystem and human health. According to the
Malaysia Environmental Quality Act 1974, industrial effluents must maintain phenol
concentrations below 1 mg/L. This study aimed to produce bamboo-activated carbon
(BAC) using a pilot-scale continuous carbonization-activation reactor. The BAC was
simultaneously carbonized at 500°C for 2 hours, followed by activation at 800°C for an
additional 2 hours within the same system, resulting in a high specific surface area of
1018 m²/g. In batch adsorption tests, BAC removed over 90% of phenol within just 15
minutes at an adsorbent dosage of 0.4 g, across a wide range of pH levels (2-12) and
initial phenol concentrations (50-300 mg/L). The phenol adsorption followed pseudofirst-order with R² values of 0.9995 and best fit the Freundlich isotherm model with an
R² value of 0.9588. These findings suggest that BAC produced in this pilot-scale system
shows great potential as an effective adsorbent for phenol and possibly other
pollutants |
