Penelitian ini bertujuan untuk mengetahui karakteristik produk hasil pembuatan arang aktif dari cangkang kelapa sawit secara aktivasi fisika, kimia dan fisika-kimia dan mengetahui kemampuan adsorpsi arang aktif dari cangkang kelapa sawit dalam uji adsorpsi dengan asam asetat 0,5 N. Proses aktivasi dilakukan secara kimia, fisika, dan fisika-kimia. Pada aktivasi secara fisika dilakukan dengan pemanasan pada suhu tinggi menggunakan furnace yaitu pada suhu 750oC selama 3 jam. Pada aktivasi secara kimia menggunakan ZnCl2 sebagai aktifator dan direndam selama 24 jam. Aktivasi secara fisika-kimia merupakan penggabungan dari aktivasi fisika dan aktivasi kimia. Kemudian dilakukan pengujian untuk mengetahui karakteristik arang aktif dan uji kemampuan daya adsorben arang aktif terhadap asam asetat. Berdasarkan hasil penelitian arang aktif yang dibuat dari cangkang kelapa sawit dengan proses aktivasi secara fisika-kimia mempunyai daya jerap yang paling baik di antara arang aktif lain yang diaktivasi dengan proses fisika dan kimia. Pada waktu penjerapan 4 jam, arang aktif berdiameter 355 µm dengan aktivasi fisika-kimia mampu menjerap sebanyak 34,4% bagian dari larutan asam asetat 0,5 N.Keywords: Arang aktif, asam asetat, aktivasi, adsorpsiThis study was carried out to investigate the characteristics of activated carbon from coconut palm shell and also the performance of activated carbon for adsorption 0.5 N acetic acid solution. Activated carbon obtained from coconut palm shell was activated by chemical, physical and combination of physical and chemical methods. Physical activation was performed by heating the carbon at 750oC for 3 hours while chemical activation process was exhibited by immersing the carbon in ZnCl2 solution for 24 hours. Furthermore, the combination of physical-chemical activation was gained by heating carbon at 750oC for 3 hours and then immersing in ZnCl2 solution for 24 hours.The adsorption performance of activated carbon was investigated by immersing activated carbon in 0.5 N acetic acid solution for specific time. The result showed that activated carbon which was obtained by combination of physical and chemical process was the best among the other methods that mentioned earlier. The highest adsorption capacity for 0.5 N acetic acid solution was achieved 34,4% for 4 hours by using355 µm of particle size..Keywords: activated carbon, acetic acid, activation,adsorption

Viscometric Study

Some ways of estimating the values of the intrinsic viscosity of chitosan were analyzed. It was shown that the method of Irzhak and Baranov for estimating the current value of the intrinsic viscosity allows to adequately estimates the conformational state of the macromolecular coil and its degree of swelling.
