Preparation of porous carbon from kenaf fibre for the adsorption of bisphenol A

Preparation of porous carbon from kenaf fibre for the adsorption of bisphenol A / Jamilah Abdullah
Tujuan kajian ini adalah untuk mengoptimumkan keadaan penyediaan karbon berliang, karbon teraktif untuk penjerapan Bisphenol A (BPA), dan untuk menentukan penjerapan BPA dari segi isoterma penjerapan dan kinetik. Prekursor adalah 1 hingga 2 mm serat kenaf. Kaedah untuk menghasilkan karbon teraktif adalah pyrolysis menggunakan asid fosforik, H3PO4 sebagai agen pengaktif. Kenaf dienapjerap dengan nisbah yang berbeza asid fosfat dan diaktifkan pada 450 ℃ selama 90 minit. Karbon teraktif kenaf (KAC) 5 berat %, 10 berat % dan 15 berat % daripada asid fosforik dihasilkan dan keputusan yang terbaik digunakan dalam ujian penjerapan. KAC yang terbaik untuk pemeriksaan yang mempunyai KAC dengan 15% berat asid fosforik yang memberikan 96.6% penyingkiran BPA pada 100 mg / L. Di samping itu, semakin tinggi kepekatan penyelesaian BPA, masa yang lebih lama diperlukan untuk menyingkirkan BPA sementara suhu operasi terbaik adalah 30 ℃. Terakhir, penyingkiran BPA boleh dilakukan dalam larutan pH 5 hingga 9. _______________________________________________________________________________________________________ The purpose of this studies was to optimize the preparation condition of porous carbon, activated carbon for the adsorption of Bisphenol A (BPA) and to establish the BPA adsorption in term of adsorption isotherm and kinetics. The precursor was 1 to 2 mm of kenaf fibre. The method to produce the activated carbon was pyrolysis using phosphoric acid, H3PO4 as activating agent. Kenaf was impregnated with different ratios of phosphoric acid and activated at 450 ℃ for 90 minutes. Kenaf activated carbon (KAC) was prepared with 5wt%, 10wt% and 15wt% of phosphoric acid and the best result will further used in the adsorption test. The best KAC for the screening is KAC with 15wt% of phosphoric acids which give the 96.6% of removal of BPA at 100 mg/L. In addition, the higher the concentration of BPA solution, the longer time needed to remove the BPA while the best operating temperature is 30 ℃. Lastly, the removal of BPA can be done in the solution at the pH 5 to 9.
