Proses elektrolisis dilakukan dengan sistem 2-kompartemen untuk menentukan kondisi konversi elektrolitik ion Mg 2+ menjadi Mg(OH) 2 . Metode yang digunakan adalah pemisahan magnesium berdasarkan pengendapan selektif melalui proses elektrolisis yang dilakukan selama 4 jam. Hasil elektrolisis kemudian dianalisis menggunakan spektroskopi FTIR dan AAS. Spektra IR membuktikan bahwa endapan hasil elektrolisis merupakan Mg(OH) 2 yang ditunjukkan pada bilangan gelombang 3695,61 cm –1 dan 3425,58 cm –1 yang menginformasikan ada gugus –OH dan bilangan gelombang 871,82 cm –1 yang mengindikasikan ada ikatan Mg-O. Rendemen Mg(OH)2 hasil elektrolisis tertinggi sebesar 99,41% pada penggunaan NaOH 0,1M. Hasil analisis AAS menunjukkan bahwa kadar Mg dalam endapan Mg(OH)2 sebanyak 55,12%.}, issn = {2597-9914}, pages = {57--60} doi = {10.14710/jksa.13.2.57-60}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/15914} }
