Abstract
Penelitian ini bertujuan untuk mengoptimalkan ekstraksi logam perak (Ag) dari limbah Printed Circuit Board (PCB) menggunakan pelarut Terniary Deep Eutectic Solvent (TDES) berbasis kolin klorida (ChCl), etilen glikol (EG), dan asam sitrat (CA). Dalam penelitian ini, dilakukan optimasi terhadap suhu pelindian, lama waktu pelindian, dan rasio solid-to-liquid (S/L) untuk menentukan kondisi yang paling efisien dalam proses ekstraksi logam perak. Analisis karakterisasi hasil sintesis TDES menggunakan uji pH, Fourier Transform Infrared Spectroscopy (FTIR), dan Differential Scanning Calorimetry (DSC) menunjukkan bahwa TDES yang terbentuk stabil dan efektif untuk proses pelindian. Proses pelindian dilakukan dengan variasi suhu 80°C, 100°C, 120°C, dan 140°C juga variasi waktu 6, 9, 12, dan 15 jam, serta rasio S/L yang berbeda (0,5/20, 1/20, 1,5/20, dan 2/20 g/mL). Setelah proses pelindian, konsentrasi logam perak yang terekstraksi dianalisis menggunakan Atomic Absorption Spectroscopy (AAS). Hasil penelitian menunjukkan bahwa suhu 120°C, waktu 9 jam, dan rasio S/L 2/20 g/mL memberikan hasil ekstraksi perak yang optimal, dengan konsentrasi perak yang terekstraksi mencapai 1.845 mg/L, dengan efisiensi ekstraksi sebesar 94.82%. Penelitian ini memberikan kontribusi penting dalam pengembangan teknologi ramah lingkungan untuk ekstraksi logam berharga dari limbah elektronik, serta meningkatkan efisiensi proses ekstraksi logam dari PCB dengan menggunakan DES berbasis kolin klorida. This study aims to optimize the extraction of silver (Ag) from Printed Circuit Board (PCB) waste using a Ternary Deep Eutectic Solvent (TDES) based on choline chloride (ChCl), ethylene glycol (EG), and citric acid (CA). In this study, optimization was conducted on leaching temperature, leaching time, and solid-to-liquid (S/L) ratio to determine the most efficient conditions for the silver metal extraction process. Characterization analysis of the synthesized TDES using pH testing, Fourier Transform Infrared Spectroscopy (FTIR), and Differential Scanning Calorimetry (DSC) showed that the formed TDES is stable and effective for the leaching process. The leaching process was carried out with variations in temperature (80°C, 100°C, 120°C, and 140°C), leaching time (6, 9, 12, and 15 hours), and different S/L ratios (0.5/20, 1/20, 1.5/20, and 2/20 g/mL). After the leaching process, the concentration of extracted silver was analyzed using Atomic Absorption Spectroscopy (AAS). The results of the study showed that a temperature of 120°C, a time of 9 hours, and an S/L ratio of 2/20 g/mL provided optimal silver extraction results, with the concentration of extracted silver reaching 1,845 mg/L and an extraction efficiency of 94.82%. This study makes an important contribution to the development of environmentally friendly technology for the extraction of valuable metals from electronic waste, as well as improving the efficiency of metal extraction processes from PCBs using DES based on choline chloride.
