Abstrak

ZnO nanopartikel disintesis dengan metode hidrometalurgi sederhana menggunakan bahan baku berupa debu tungku busur listrik yang merupakan limbah padat industri baja tahan karat. Debu busur listrik mengandung 68,81% Zn dalam bentuk zincite (ZnO) dan simonkolleite (H10Cl2O9Zn5). Proses sintesis dilakukan dalam dua tahap utama yaitu pelindian dan pengendapan alkali. Pada penelitian ini dipelajari pengaruh reagen pelindian, suhu pelindian, dan konsentrasi reagen pelindian pada proses pelindian terhadap persen ekstraksi Zn dari debu tungku busur listrik dan karakteristik produk ZnO yang dihasilkan. Hasil percobaan menunjukkan bahwa asam asetat adalah reagen pelindian yang memberikan persen ekstraksi Zn tertinggi. Hasil percobaan juga menunjukkan bahwa semakin tinggi suhu dan konsentrasi asam yang digunakan, maka semakin meningkat persen ekstraksi Zn yang diperoleh. Tetapi pada konsentrasi asam 2M, suhu pelindian tidak terlalu berpengaruh karena dengan konsentrasi asam asetat 2M pada semua kondisi suhu pelindian, persen ekstraksi Zn yang diperoleh adalah 100%. Hasil pelindian menggunakan asam asetat pada kondisi optimum menghasilkan produk ZnO dengan kemurnian sekitar 96%. Data XRD juga menunjukkan bahwa ZnO yang terbentuk memiliki ukuran nano.
