Optimization of Copper Dissolution from Electronic Waste Printed Circuit Board Using Leaching Method

Electronic waste contains hazardous materials which have an adverse impact on the environment. Therefore, a solution is needed to recycle electronic waste. One recovering copper metal from Printed Circuit Board (PCB) in The dissolution of carried out by leaching method, means dissolving using selective solvent. Analysis was performed Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES). This experiment aims determine factors that influence optimization PCB method and analysis content ICP-OES. primary data obtained per cent recovery each factor affects dissolution, concentration sulfuric acid as solvent, percentage solid / liquid, speed stirring, temperature, length stirring. optimum conditions were achieved form highest variation, 9.8% acid, 5% solid/liquid percentage, 200 rpm stirring speed, at temperature 60 °C with time 120 minutes, respectively 79.83%; 74.86%; 76.52%; 54.84%.Keywords: electronic, waste, PCB, Optimalisasi Pelarutan Tembaga dari Limbah Elektronik dengan Metode LeachingABSTRAKLimbah elektronik mengandung bahan-bahan berbahaya yang berdampak buruk bagi lingkungan. Oleh sebab itu, diperlukan solusi untuk mendaur ulang limbah salah satunya adalah pengambilan kembali atau logam tembaga pada elektronik. dilakukan metode leaching, yaitu melarutkan menggunakan pelarut selektif. Analisis terhadap kadar Percobaan ini bertujuan mendapatkan faktor-faktor berpengaruh optimalisasi pelarutan analisis Data primer diperoleh persen setiap memengaruhi tembaga, konsentrasi asam sulfat sebagai pelarut, persentase solid/liquid, kecepatan pengadukan, suhu, dan lama pengadukan. Kondisi dicapai berupa tertinggi variasi, 9,8% sulfat, pengadukan rpm, suhu menit secara berturut-turut 79,83%; 74,86%; 76,52%; 54,84%.Kata kunci : elektronik, limbah,
