Removal of Fe2+ (iron) from batik industries’ effluent by using activated carbon from mangrove timber prepared via physiochemical activation

Removal of Fe2+ (iron) from batik industries’ effluent by using activated carbon from mangrove timber prepared via physiochemical activation / Mohamad Alif Abdullah
Dalam kajian ini, terdapat pelbagai jenis karbon teraktif yang dihasilkan daripada kayu bakau dengan menggunakan kalium hydroksida sebagai agent pengaktif. Karbon teraktif dicirikan dengan menggunakan thermogravimetric analyzer, brunauer-emmettteller dan elemental analyzer. Penjerapan Ion Fe2+ diuji dengan menggunakan karbon teraktif yang dihasilkan. Terdapat pelbagai faktor yang dapat memberi kesan terhadap penyingkiran Ion Fe2+ dikaji dengan melalui suhu pengaktifan dan nisbah kalium hydroksida digunakan. Penyikiran Ion Fe2+ optimum diperolehi dengan menggunakan karbon teraktif pada keadaan suhu pengaktifan 850 °C dan nisbah kalium hydroksida digunakan adalah 1.5. Keputusan maksima sebanyak 57.86 % untuk penyingkiran Ion Fe2+ didapati dengan menggunakan kepekatan asal pada 50 mg/L. Penjerapan Ion Fe2+ pada karbon teraktif berasaskan kayu bakau didapati sesuai dengan penjerapan isotema Langmuir dan pseudo kinetik model kedua. Hasil kajian ini menunjukkan bahawa karbon teraktif yang disediakan daripada kayu bakau merupakan penjerap yang sesuai untuk menjerap Ion Fe2+ daripada larutan akueus. _______________________________________________________________________________________________________ In the present study, different activated carbons were prepared from carbonized mangrove timber by potassium hydroxide activation agent. The activated carbons were characterized by thermogravimetric analyzer, brunauer-emmett-teller and elemental analyzer. The Fe2+ ions adsorption of the prepared carbons was evaluated. The different factors affecting Fe2+ ions removal were studied which are the activation temperature and ratio of KOH impregnation. The optimum Fe2+ ions removal was obtained at activated carbon with parameter 850 °C of activation temperature and 1.5 of KOH impregnation ratio. The maximum removal percentage were determined at 50 mg/L initial Fe2+ concentration at 57.86 %. The adsorption of Fe2+ ions on mangrove based activated carbon was found to follow the Langmuir adsorption isotherm and pseudo second order kinetic model. The result of adsorption study showed that the activated carbon prepared from mangrove timber is a suitable adsorbent for Fe2+ ions removal from aqueous solution.
