Abstract

One of the contaminant liquid waste pollution from processing gold mines is mercury (Hg). Mercury as primary pollutant from gold processing will be processed using activated carbon derived from coconut shell charcoal. The purpose of the absorption of mercury liquid waste is to reduce mercury levels to a minimum so that it can meet levels of pollution that meet environmental quality standards of 0.005 ppm. Experiments were carried out with variations in the concentration of NaOH as an activator and the mass active carbon variation from the coconut shell. First the coconut shell charcoal will be sieved using a 100 mesh screen, then the activation process will be carried out with an alkaline activator. Coconut shell charcoal which has been activated after being analyzed using a mercury analyzer has been shown to reduce levels of mercury in wastewater. Experiments based on variations in NaOH concentration showed maximum results at a concentration of 0.5 N which is 0.0049 ppm, whereas based on variations in the mass of activated carbon it was shown by a 3 gram carbon mass with maximum absorption results of 0.0035 ppm. Based on the two experimental results above, the mercury levels produced have met the permitted environmental quality standards. The analysis is then continued using the Langmuir Isotherm equation, BET, Freundlich and Temkin to find the right adsorption isotherm model. Based on the Isotherm analysis generated by the exact adsorption isotherm model in this experiment is Langmuir with a coefficient of determination (R2) of 0.998.
