Abstract

Telah dilakukan penelitian tentang pengaruh ligan NH₃ pada pengambilan logam tembaga dari serpihan sisa produksi kuningan Kabupaten Pati secara elektrolisis. Serpihan sisa produksi kuningan mengandung logam mayor yakni tembaga(Cu), seng(Zn), dan logam minor yakni Timbal(Pb), dan Timah (Sn). Penambahan ligan tertentu dapat meningkatkan kuantitas dan kualitas endapan. Penelitian ini meliputi 3 langkah, yaitu destruksi serpihan sisa produksi kuningan, elektrolisis dan analisis dengan AAS. Larutan elektrolit yang digunakan adalah larutan hasil destruksi serpihan kuningan yang diencerkan 1000 kali. Variabel penelitian ini adalah waktu elektrolisis yaitu 30, 60, 90, dan 120 menit pada sampel tanpa dan dengan penambahan NH₃. Hasil penelitian menunjukkan bahwa berat endapan 19,54 mg tanpa ligan NH₃ dan 20,58 mg dengan ligan NH₃ pada waktu elektrolisis 120 menit. Kemurnian endapan tembaga pada waktu elektrolisis 30 menit pada sampel tanpa penambahan NH₃ adalah 62,80% dan dengan penambahan NH₃ 72,46%.
