Abstract

The industry of sasirangan – traditional fabric of Banjar Tribe – has been one of prime commodities of South Kalimantan. The coloring process  in sasirangan production used a lot of chemical elements containing heavy metals  and its waste potentially pollute the environment. One of the heavy metal waste contained is copper (Cu) which is toxic to aquatic organisms and humans. The treatment for sasirangan liquid waste can be done by adsorption process using activated carbon as adsorbent. This study aims to determine the appropriate kinetic model for adsorption of Cu metal from sasirangan liquid waste using activated carbon adsorbent made from rice husks.The process was conducted by batch system with chemical and physical activation. Chemical activation was done by soaking the activated carbon of rice husk with HCl solution for 24 hours. While physical activation was carried out by burning in a furnace at 500̊C for 2 hours. The adsorption treatment was given on sasirangan waste samples with variations on contact time (30, 60 and 120 minutes). The results of kinetics study showed that the adsorption process of Cu from sasirangan liquid waste onto rice husk activated carbon adsorbent followed first-order reaction kinetics with a correlation coefficient value (R2) of 0.96 and adsorption rate constant (k1) of 0.0044 min-1.

Abstract

South Kalimantan is one of the textile industry producers, which is Sasirangan industry.The traditional fabric-making process involves chemicals as the production process. Sasirangan liquid waste contains pollutants that do not meet the requirements for disposal into the environment, including cadmium (Cd). Adsorption process is an effective method to reduce heavy metal concentrations in liquid waste. This study aims to determine the potential of rice husk activated carbon in adsorbing Cd metal from  sasirangan liquid waste and to analyze the effect of stirring speed on the adsorption process. The rice husks that had been carbonized were then activated chemically and physically. Chemical activation process was carried out by adding chemical compound HCl which was immersed for 24 hours. Furthermore, it was physically activated in the furnace for 45 minutes at 4500C. In case to get optimum result, the effect of stirring speed on the adsorption process was studied. The stirring speed determines the rate of adsorbent and adsorbate contact time. The higher the stirring speed, the higher the decrease in Cd content because adsorbate absorption process by  adsorbent is getting better. The greatest decrease in Cd concentration was by carbon that had been activated  with a stirring speed of 90 rpm where the remaining Cd content in the sample was 0.018 mg / L.
