Description
Dye pollution is one of the organic pollutants that is well known for endangering both humans and aquatic life. Dyes can prevent access to the photic zone of the aquatic environment and interfere with the absorption and reflection of sunlight. Wastewater that has been dye-contaminated needs to be carefully treated in order to lessen its harmful effects. One of the common methods used to treat dye wastewater is adsorption with activated carbon (AC). This is due to AC properties, which have high porosity, a large surface area, internal structure, and the presence of different surface functional groups. This study focuses on utilising the oil palm trunk (OPT) fibre to produce AC for the adsorption of methylene blue (MB). Two types of fibre, parenchyma and vascular bundle, from the OPT were impregnated with different amounts of 85% phosphoric acid (H3PO4) and then carbonised at 600 °C for 1.5 hours. The synthesised AC were characterised physically and chemically using BET, SEM, FTIR, adsorption experiments, etc. The cationic MB dye was used to assess the efficiency of the synthesised AC and critically select the most suitable precursor for the adsorption experiments with different parameters such as the dosage of adsorbent, pH, initial dye concentration, and temperature of the solution. The obtained adsorption experimental data were fitted to adsorption isotherm models such as Langmuir, Temkin, and Freundlich and kinetic models such as pseudo first and second order to understand the adsorption process.
