| Abstract |
The development of the textile and printing industries has led to an increase in colored wastewater containing methylene blue substances that are difficult to degrade by the environment. This study aimed to investigate the effect of catalyst dose, solution pH, and the addition of H2O2 on the catalytic activity of Fe-impregnated activated carbon in removing methylene blue. The impregnation of the Fe catalyst on activated carbon made from kepok banana peel overcame the problems. The quality of activated carbon was measured based on its water content of 7.01 %, the fixed carbon content of 65.50 %, the ash content of 9.90 %, and the iodine absorption of 1,243.62 mg/g. Based on the test results on activated carbon, the four parameters were obtained following the Indonesian National Standard. The SEM-EDX tests showed that the morphology of Fe-impregnated activated carbon had an irregular and porous shape with a Fe content of 4.39 %. The maximum removal efficiency of methylene blue in the Fenton process (with H2O2) with variations in catalyst dose and reaction time of 120 min is 61.12 % (2 g/L); 90.13 % (4 g/L); 95.28 (6 g/L), and 95.40 % (8 g/L). The degradation kinetics of the Fenton process with the activated carbon-Fe catalyst corresponds to the first-order reaction kinetics. This study showed that the product catalyst could achieve high removal efficiency and stability. Additionally, the product can support a circular economy strategy for the Indonesian government, increase the value of kepok banana waste, and lessen the amount of garbage released into the environment. |
