Abstract

The research about adsorption of Rhodamine B dye by active carbon from Durian shell has been done. The active carbon gained from carbonation process which is shell of Durian put into furnace at 350 oC during 2 hours, and then being cold and sieved with 100 mesh sieves. Next process was calcinations at 450 oC C flowed by N2 gases for 2 hours then characterized with XRD spectrophotometer. Activation process is done through submerge of carbon in 3 M of KOH solution for 15 hours and dried in oven at 110 oC for 1 hour, then characterized with XRD. After that, adsorption process toward Rhodamine B dye and the result was tested using UV-Vis spectrophotometer. The results show that optimum condition from active carbon was at adsorbent weight of 0.6 g with contact time 100 minutes at pH 3.0 for adsorbs Rhodamine B concentration of 50 ppm. Adsorption of Rhodamine B dye fitted Freundlich isotherm with correlation coefficient (R2), K and n value were 97.3 %, 21.542 mg/g, and 0.405 respectively.
