Kesetimbangan Adsorpsi Isotermal Logam Pb Dan Cr Pada Limbah Batik Menggunakan Adsorben Tongkol Jagung (Zea Mays)

Abstract

Batik sebagai salah satu potensi yang ada di Indonesia terkadang menggunakan pewarna sintetis yang mengandung bahan kimia. Limbah yang dihasilkan bisa jadi masih mengandung logam berat yang mempunyai toksisitas yang tinggi. Logam berat pada limbah batik yang mempunyai toksisitas tinggi tersebut antara lain logam timbal (Pb) yang biasanya berasal dari pewarna putih dan Kromium (Cr) dari pewarna merah. Solusi yang ditawarkan untuk mengurangi kadar Pb dan Cr pada limbah batik adalah melakukan proses adsorpsi menggunakan tongkol jagung. Tujuan dari penelitian ini untuk mengetahui model kesetimbangan yang digunakan untuk melihat keefektifan tongkol jagung sebagai adsorben logam Pb dan Cr adalah Langmuir dan Freundlich dengan variasi konsentrasi Pb yaitu 10, 25, 50, 75, 100, 150 dan 200 mg/L dan Cr pada konsentrasi 500, 600, 700, 800, 900 dan 1000 mg/L. Model kesetimbangan isotherm adsorpsi logam Pb dan Cr menggunakan tongkol jagung dengan waktu kontak 60 menit, kecepatan pengadukan 100 rpm dan 150 rpm. Hasil analisis kesetimbangan adsorpsi isotherm Langmuir untuk logam Pb dan Cr menghasilkan kapasitas adsorpsi 4,25mg/g dan 4,46 mg/g. Analisis kesetimbangan adsorpsi isotermal Freundlich untuk logam Pb dan Cr menghasilkan tetapan kesetimbangan 3,31 dan 3,41. Kesimpulannya adalah model kesetimbangan adsorpsi Langmuir lebih sesuai digunakan untuk menentukan keefektifan proses adsorpsi logam Pb dan Cr menggunakan tongkol jagung pada limbah batik dibandingkan dengan model Freundlich.
