Abstract

Penelitian ini bertujuan untuk mensintesis dan menguji kemampuan karbon aktif dalam menyerap logam berat yang terlarut dalam air. Karbon aktif dibuat dari kulit pisang yang telah dikeringkan. Sintesis karbon aktif dilakukan dengan penambahan aktivator H2SO4 dengan variasi 20%, 25%, 30%, dan 35%. Aktivator berfungsi dalam membuka pori karbon, sehingga dapat memperluas permukaan absorbsi karbon aktif tersebut. Kinerja karbon aktif ini dilihat pada daya absorbsinya terhadap logam berat yang terdapat pada limbah tambang emas di sungai Batang Palangki Kabupaten Sijunjung. Dimana, sebelumnya telah dilakukan pengujian kandungan logam berat dari limbah tersebut menggunakan Inductively Coupled Plasma (ICP), dan ditemukan 24 unsur logam berat yang mana 8 diantaranya diatas ambang batas syarat baku mutu air bersih. Berdasarkan hasil penelitian, karbon aktif dengan penyerapan yang paling optimal yaitu pada konsentrasi aktivator H2SO4 35%. Karbon aktif tersebut dapat menyerap 90% logam berat dari limbah.
