An oil palm empty fruit bunch-derived activated carbon has been successfully produced by chemical activation with zinc chloride and without chemical activation. The preparation was conducted in the tube furnace at 500 o C for 1 h. The surface structure and active sites of activated carbons were characterized by means of Fourier transform infrared spectrometry and field emission scanning electron microscopy. The proximate analysis including moisture content, ash content, bulk density, pH, and pH

The results showed that the zinc chloride-activated carbon has better characteristics compared to the carbon without chemical activation. Abstrak Karbon teraktif yang diperolehi dari tandan buah kosong kelapa sawit telah berjaya dihasilkan melalui kaedah pengaktifan kimia zink klorida dan juga tanpa pengaktifan kimia. Penyediaan ini dijalankan dalam relau tiub pada suhu 500'C selama 1 jam. Spektroskopi Inframerah Transformasi Fourier dan Mikroskopi Imbasan Elektron Pancaran Medan digunakan untuk menganalisis stuktur permukaan dan juga tapak aktif pada karbon teraktif. Analisis yang lain termasuk kandungan lembapan, kandungan abu, ketumpatan pukal, pH, konduktiviti dan pH pada cas kosong telah dijalankan untuk mengenal pasti ciri-ciri kimia fizik bahan penjerap. Hasil kajian menunjukkan bahawa karbon teraktif-zink klorida mempunyai ciri-ciri yang lebih baik berbanding dengan karbon tanpa pengaktifan kimia.
