ABSTRACT: This research is
conducted to produce carbons from coconut fibre which approach to activated
carbon clause continue with carbon surface modification and the adsorption
examination to Cu(II) ions. The research consist of several phase. Carbon
making of coconut fibre conducted by carbonization processes at 320-400oC with
temperature interval 20oC. Carbon yielded in characterized moisture content,
ash content and its adsoprtion to iodium. The carbon surface modification
conducted by loaded 2-mercaptobenzotiazol (MBT) on carbon. The adsorpsibility
of carbon-MBT tested by influence of contact time, pH, and the isoterm
adsorption pattern. The result of the study showed carbonization of coconut
fibre which approach the requirement of SII No.0258-89 gained at temperature
320oC. In the present study equilibrium time of 10 minute and pH was found to
be optimum for both adsorbent. While type of isothermal adsorption from carban
and carbon-MBT adsorbent followed the Langmuir adsorption pattern.
