AUSTRALIAN PINE CONES-BASED ACTIVATED CARBON FOR ADSORPTION OF COPPER IN AQUEOUS SOLUTION MUSLIM A. Department of Chemical Engineering, Syiah Kuala Univeristy No. 7JalanTgk. Syech Abdul Rauf, Darussalam, Banda Aceh Indonesia Corresponding Author: Abstract The Australian Pine cones (APCs) was utilised as adsorbent material by physical and chemical activation for the adsorption Cu(II) from aqueous solution. FTIR and SEM analysis were conducted to obtain the active site and to characterise the surface morphology of the APCs activated carbon (APCs AC) prepared through pyrolysis at 1073.15 K and the alkaline activation of NaOH. The independent variables effect such as contact time, Cu(II) initial concentration and the activator ratio in the ranges of 0-150 mins, 6.5-370.5 mg/l and 0.2-0.6 (NaOH:APCs AC), respectively on the Cu(II) adsorption capacity were investigated in the APCs activated carbon-solution (APCs ACS) system with 1 g the APCs AC in 100 ml Cu(II) aqueous solution with magnetic stirring at 75 rpm, room temperature of 298.15 K (± 2 K), at 1 atm and normal pH. As a result, Cu(II) adsorption capacity dramatically increased with…show more content…
To start an experiment of adsorption isotherm, Cu(II) aqueous solution of 100 ml with the predetermined varying initial concentration of Cu(II) in the range of 6.5-370.5 mg/l and the best activator composition of NaOH was put into the erlenmeyer flask and stirred using a magnetic stirrer at 75 rpm, room temperature of 298.15 K (± 2 K), 1 atm and normal pH. The experiment was stopped at 119 mins contact time for sampling. The samples of 1 ml were placed in a 20-ml vial and diluted with 10 ml distilled water, and filtered using a syringe filter. The filtrate was placed in 10-ml vial for the AAS analysis. To determine the concentration Cu(II) in the samples from the AAS reading, dilution factor was taken into
