Cangkang telur merupakan limbah rumah tangga yang melimpah. Penelitian ini bertujuan untuk melakukan investigasi model kesetimbangan yang terjadi pada proses adsorbsi ion logam nikel(II) menggunakan cangkang telur sebagai adsorben. Proses adsorbsi menggunakan metode batch dengan waktu kontak tetap (60 menit) dan konsentrasi awal larutan nikel(II) yang berbeda-beda. Persentase efektifitas adsorbsi maksimum sebesar 93.91% menunjukkan cangkang telur cukup efektif digunakan sebagai alternatif adsorben dalam proses pengolahan logam nikel(II) pada limbah cair. Model kesetimbangan proses adsorbsi mengikuti model isotherm Langmuir dengan nilai kapasitas adsorbsi sebesar 1.99 mg/g.
