Abstract

ABSTRAK Concentration of reactive dyes and heavy metals in textile waste may be dangerous for aquatic ecosystems. One way elimination for reactive dyes and heavy metals that use coal combustion residues (bottom ash) which had been activated as an adsorbent. The purpose of this study to find out the ability of bottom ash as an adsorbent reactive dyes and heavy metals (Cu and Ni). Adsorption process uses two reactors are fed adsorbate with the continuous method, using 25 g of adsorbent mass in the reactor 1 and 2. When sampling is done every 30 minutes for 3 hours, then tested the color parameters and heavy metals (Cu and Ni). The results showed a decrease of dye 13 750 Pt to 240 Pt-Co, whereas for the decrease in concentration of the metal adsorption is not stable so it is said to be ineffective. The resulting efficiency for the dye concentration reaches 97%, while the saturation time for the adsorption of the dye is shown in the minute-240 with a ratio of 1 g of adsorbent can reduce the color up to 94.5 Pt-Co. Key words: adsorption, adsorbents, reactive dyes, heavy metals.
