Characterization of Activated Carbon from Mangrove Propagule Waste (Rhizophora Mucronata) Activated by Hydrochloric Acid (HCL)

The development of industry often raises problems related to the waste produced. The waste produced causes odor, color, and taste. One way to overcome this problem is by the adsorption method. The adsorption method that is oftenly used is using activated carbon as an adsorbent. The study aims to determine the characteristics of activated carbon from mangrove propagules activated using hydrochloric acid (HCl). Activated carbon is an amorphous carbon with a very large surface area, which is 200 to 2000 m2/g. The basic material of activated carbon is Lignocellulose. Mangrove propagules waste is a biomass containing lignocellulose. Hydrochloric acid (HCl) which acts as an activator is hygroscopic, so it can reduce the water content in the activated carbon produced. Testing is carried out by SNI and SII, including physical tests and absorption of Iodine. The carbonization temperature variables used three temperature variables: 300, 400, and 500 °C, and HCl concentrations: 1, 2, 3, and 4 N. In general, it had met the quality standards set by SII No. 0258-79 and SNI No. 06-3730-1995.
