Abstract

 

In this study, coal samples are synthesized from durian peel (the outer protective layer of durian fruit) by drying, mincing, and putting into a sieve with a fine mesh of 1-2 micrometers. Coal samples are activated by 2M NaOH solution with 1:20 (w/v) ratio for 2 hours and then heated at 700 degrees Celsius for 1 hour to create activated carbon. After preparation, samples are analyzed using advanced analytic techniques such as FTIR spectroscopy and SEM. The adsorption of activated carbon on the Reactive Blue 220 dye is investigated. Results show that the adsorption of the material is affected by the concentration of Reactive Blue 220, which, therefore, needs to be controlled in the adsorption process. In addition, optimal parameters are also investigated for the best adsorption condition, particularly at pH=7 with dye concentration at 10 ppm, 20 ppm, 30 pmm, and 40 ppm with the addition of 0.2 grams of coal and exposed for 3 hours and 30 minutes (210 minutes). The color removal efficiency is found to be 92.64% (for 10 ppm concentration of Reactive Blue 220). The Langmuir adsorption model is applied and the maximum adsorption capacity is 21.053 mg/g.
