Abstract

Activated carbon was produced from high-grade bituminous coal, potentially removing Cr metal in textile industrial waste. The purposes of this study were 1) getting activated carbon characteristics, 2) studying the impact of reagent concentration and activation temperature on the activated carbon characteristics, and 3) getting the isotherm adsorption equation for activated carbon developed by Freundlich and Langmuir on Cr metal. This research used an experimental method with a laboratory scale, which means the manufacture of activated carbon and a test of adsorbs power of activated carbon to the Cr metal were conducted in the laboratory. Activated carbon manufacture through carbonization process of chemical activation used reagent (NH₄)₃PO₄, neutralization, filtration, physical activation, and cooling. At the same time, it tested the adsorption power of the activated carbon to Cr metal through activated carbon contact with a solution containing some Cr⁶⁺ ion. The update in this research was using reagent (NH₄)₃PO₄ and the test of adsorption power of activated carbon to Cr⁶⁺ ion contained in the artificial waste. This research showed activated carbon that has been activated using reagent (NH₄)₃PO₄ 0.5 – 2 M at physical activation temperature of 825^oC and has met the standard of SNI number 06-3730-1995. The best-activated carbon was produced from chemical activation using (NH₄)₃PO₄ 1 M solution and physical activation at 825^oC. The best-activated carbon characteristics contained 1.27% water; 17.17% content of volatile matter, 9.39% was ash content; 73.17% contained fixed carbon, and the iodine value was 1248.30 mg/g. The best Equation of Langmuir isotherm adsorption of activated carbon to the Cr⁶⁺ produced Constant Ar = -90.0901 and Kc = -0.0075.
