Abstract
The decolorization of synthetic melanoidin solution by activated charcoal adsorption was investigated using 2^k factorial. The effect of the factors initial pH (3,7), activated charcoal dosage (3.33 g/L, 6.67 g/L) and activated charcoal size (0.48 mm, 1.37 mm) on percent decolorization and final pH of the solution was determined. Twenty four experimental runs of different initial conditions were carried out and the data were obtained after 24 hours. Based on the analysis of the variance, final pH and percent decolorization were affected by initial pH, activated charcoal dosage, and the interaction of final pH and activated charcoal dosage. The highest percent decolorization of 35.95±15.97% was obtained at pH 3, 3.33 g/L adsorbent dosage and 1.37 mm size. This initial condition was used in fitting the adsorption of melanoidin to activate charcoal to isotherms. Among the isotherms tested, Langmuir isotherm best fits the data for the adsorption of melanoidin on activated charcoal.
