Abstract

Biosorpsi merupakan salah satu metode alternatif untuk menyisihkan logam berat dengan memanfaatkan bahan biologis. Biosorpsi telah dipilih karena memiliki biaya operasi yang rendah, ramah lingkungan, dan juga penggunaan biomaterial terbarukan yang melimpah secara alami. Permintaan akan Platinum Group Metal (PGM) pada dasarnya tinggi. Namun keberadaan PGM di alam sangat terbatas. Biosorben umum untuk ion logam mulia mencakup berbagai turunan kitosan, serta senyawa lain dengan kandungan gugus fungsi amina permukaan yang relatif tinggi. Kitosan dicampur dengan PVA dengan crosslinker glutaraldehida untuk menstabilkan kitosan dalam keadaan asam. Untuk memenuhi tujuan penelitian, maka dilakukan proses pengujian SEM-EDX, UV-VIS dan juga FTIR. Hasil penelitian menunjukkan bahwa kitosan merupakan adsorben yang efektif dalam menyerap ion logam Pt yaitu terjadi pada adsorben CS/PVA dengan luas permukaan 352 mm2 dan rasio konsentrasi kitosan 2 gram dengan persentase adsorpsi sebesar 47,9%. ====================================================== Biosorption is an alternative method to remove heavy metals by utilizing biological materials. Biosorption has been chosen because it has low operating costs, is environmentally friendly, and also uses renewable biomaterials that are abundant in nature. The demand for Platinum Group Metal (PGM) is in fact high. However, the existence of PGM in nature is very limited. Common biosorbents for precious metal ions include a variety of chitosan derivatives, as well as other compounds with a relatively high content of surface amine functional groups. Chitosan is mixed with PVA with a glutaraldehyde crosslinker to stabilize chitosan in an acidic state. To fulfill the research objectives, the SEM-EDX, UV-VIS and FTIR testing processes were carried out. The results showed that chitosan was an effective adsorbent in absorbing platinum metal ions, which occurred in CS / PVA adsorbent with a surface area of 352 mm2 and a concentration ratio of 2 grams of chitosan with an adsorption percentage of 47,9%.
