Abstract

Bentonit dan karbon adalah bahan yang biasanya menyerap zat warna dan pengotor pada minyak. Kemampuan bentonit dan karbon dapat ditingkatkan dengan aktivasi untuk memperbesar luas permukaan. Tujuan dari penelitian ini adalah mengadsorpsi minyak plastic untuk meningkatkan kualitasnya. Adsorpsi ini mengunakan variable warna, sulfur dan nilai kalor. Proses aktivasi karbon mengunakan akitivator KOH sedangkan bentonit menggunakan pemanasan 110 0C. Hasil penelitian ini menunjukan bahwa pencampuran karbon aktif dan bentonit memberikan pengaruh terhadap nilai kalor dan kandungan sulfur setelah proses adsorbsi pada minyak plastic yang dihasilkan. Kata Kunci: Bentonit, karbon, minyak plastik, bensin, adsorpsi.

Abstract

Rhodamine B is an organic dye commonly used in the textile industry, but it is toxic. Therefore, a photodegradation method using Fe3O4/activated carbon (AC)/ZnO nanocomposite is necessary to address environmental issues caused by rhodamine B. The Fe3O4/AC/ZnO nanocomposite has been successfully synthesized using the sonication method. Iron sand is used as a source of magnetite (Fe3O4), coconut shells as a source of activated carbon, and Zinc nitrate as a source of ZnO. XRF results show that the Fe content in iron sand is 74.10%. The ratio of Fe3O4 addition used in Fe3O4/AC/ZnO nanocomposite is 0:1:1; 1:1:1; 2:1:1; 3:1:1; 4:1:1. XRD characterization shows that the 1:1:1 ratio of Fe3O4/AC/ZnO nanocomposite has the smallest crystal size of 48.17 nm. The addition ratio of Fe3O4 does not affect the structure of the formed Fe3O4/AC/ZnO nanocomposite. Fe3O4/AC/ZnO nanocomposite is formed at 2theta 30.23°; 35.60°; 57.11°; and 62.83° for Fe3O4, peak broadening at 26.72° and ~44.71 for AC, and 31.82°; 34.47°; 36.30°; 47.59°; 56.63°; 62.89° and 67.98° for ZnO. SEM results show particle sizes of 57.95 nm for ZnO and 42.74 nm for Fe3O4/AC/ZnO 1:1:1 nanocomposite. VSM showed saturation magnetism of 4.41 emu/g for Fe3O4/AC/ZnO 1:1:1 nanocomposite and 28.8 emu/g for Fe3O4. The photocatalytic test showed that the Fe3O4/AC/ZnO 1:1:1 nanocomposite had the best % degradation of rhodamine B, at 96.1%, under sunlight.
