Pembuatan Karbon Aktif Dari Batubara Subbituminus Sebagai Adsorben Ion Logam Mn+2

---

Activated carbon can be made from materials that contain carbon, both from plants, animals and minerals. One of the minerals that can be used as a source of activated carbon is coal. Subbituminous type coal has sufficient carbon and energy content, high moisture in air-dry, volatile substances and organic minerals. Activated carbon is an absorbent material that is widely used by industry. This study aims to determine the effect of variations in the concentration of activating agents on the quality of activated carbon from subbituminous coal and the percentage of activated carbon adsorption on Mn+2 metal ions. The process of making activated carbon from subbituminous coal consists of two stages, namely carbonization and activation. Carbonization is carried out at 470 ℃ and takes place continuously in a fluidized carbonizer that produces coalite. Coalite activation is carried out at 28 ℃, soaking time is 16 hours and the activating agent used is H3PO4 concentration of 3 M and 4 M. For the process of determining the percentage of adsorption performed at pH 3, stirring speed of 200 rpm, contact time of 1 hour, activated carbon 0.1 g and Mn+2 ion concentration of 5 ppm, 10 ppm, 25 ppm and 60 ppm. The results showed that the quality of activated carbon produced had fulfilled SNI 06-3730-1995 for the parameters of Moisture in air-dry (Mad), Ash content (AC), volatile matter (VM) levels, except the Fixed Carbon (FC) parameter. The best percentage of activated carbon adsorption on Mn+2 metal ions was obtained for the activation of 4 M H3PO4 Mn+2 concentration of 10 ppm which is 65.24% and the lowest was the activation of 3 M H3PO4 concentration of Mn+2 60 ppm concentration which was 53.134%. Activated carbon activated with 3 M H3PO4 has Ash 9.83% (adb), FC 62.16% (adb), Mad 3.75% (adb), and VM 24.26% (adb) and which is activated with 4 M H3PO4 have Ash 7.66% (adb), FC 64.64% (adb), Mad 3.52% (adb), and VM 24.18% (adb). From the results of this study it can be concluded that the activated carbon from the produced subbituminous coal has a quality in accordance with SNI 06-3730-1995 (except FC parameters) and can be used as an adsorbent for Mn+2 metal ions.
