Penelitian ini bertujuan untuk melakukan studi kinetika adsorbsi logam nikel dengan limbah cangkang telur sebagai adsorben. Proses adsorbsi dilakukan dengan menggunakan metode batch. Variasi yang dilakukan adalah variasi waktu kontak. Persentase efektifitas adsorbsi  optimum diperoleh sebesar 85.66%. Model kinetika pseudo pertama, pseudo kedua, dan difusi intrapartikel digunakan untuk menjelaskan proses kinetika adsorbsi. Proses adsorbsi logam nikel terbagi menjadi dua tahap proses difusi dan mengikuti model kinetika orde kedua dengan nilai konstanta laju sebesar 0.05 mg/g.menit. Berdasarkan pada hasil penelitian ini, limbah cangkang telur cukup efektif dimanfaatkan sebagai adsorben dalam pengolahan logam nikel pada limbah cair
