Synthesis of activated spherical-like carbon (ASC) by gelatin soft templating route for inflammatory drug adsorption
Maria Ulfa and Mega Viendrieana
Synthesis spherical like-carbon have been successfully ready done this work by using gelatin as natural soft template combined with spolyoxyethylene-Polyoxypropylene block copolymer as second template and sucrose as carbon precursor. After first reaction of gelatin, block copolymer and sucrose, the mixture have catalyzed by sulfuric acid followed by hydrothermal, evaporation, carbonization and pyrolized nitrogen atmosphere reaction.. The spherical like-carbon then activated by potassium hydroxide for obtain activated spherical like-carbon (ASC) followed by filtering and drying. The characterization of activated spherical like-carbon (ASC) have been done by scanning electron microscopy and fourier transform of infra red. Activated spherical like-carbon (ASC) have applied as adsorbent of ibuprofen with initial concentration 0,1 mg/g and weight of carbon its is about 20 mg adsorben. The adsorption kinetic investigated by uv-vis spectrophotometer. The morphology observation shows that activated spherical like-carbon (ASC) have spheric structure with the range size closely with 1-10 µm. The numerous carbonyl and hydroxyl functional group by FTIR observation was predicted increase as the interaction impact between ibuprofen and adsorbent. The interesting phenomenon was observed which is the increasing adsorption capacity of activated spherical like-carbon (ASC) as well equal as the increasing activation temperature.
