“…Results are similar with two different inorganic membranes showing that, with these membranes, the Eu 3+ /La 3+ separation is a function of the permeability of the complex. This phenomenon is different to the one observed with organic membranes [3,4]. Using inorganic membranes with either TiO 2 /ZrO 2 or TiO 2 active layer, free Ln(III) are repelled by the membrane whereas the complex Ln(III) can pass through the membrane.…”

Abstrak: Saat ini telah banyak dilakukan penelitian mengenai pemisahan unsur tanah jarang karena peranannya penting dalam perkembangan teknologi. Pemisahan dan pemurnian unsur tanah jarang sangat sulit dilakukan karena unsur tanah jarang memiliki kemiripan sifat antara satu dengan yang lainnya.Oleh karena itu, perlu dilakukan pengembangan metode-metode pemisahan dan pemurnian unsur tanah jarang dari mineralmineralnya, salah satunya dengan membran nanofiltrasi dengan penambahan ligan dietilentriaminpentaasetat (DTPA).Penelitian ini bertujuan untuk memisahkan gadolinium(III) dan samarium(III) dengan menggunakan membran nanofiltrasi. Metode yang digunakan dalam penelitian adalah pembuatan larutan standar gadolinium(III) dan samarium(III), pembuatan larutan kompleks dan pemisahan dengan membran nanofiltrasi pada variasi tekanan 2-6 bar dan suhu 20-40°C. Permeat hasil dari pemisahan kemudian dianalisis dengan menggunakan ICP-AES. Dari hasil penelitian ini diperoleh tekanan optimum yaitu 2 bar dengan menghasilkan rejeksi Gd-DTPA sebesar 97,52 % dan Sm-DTPA sebesar 97,28 %. Suhu optimum yang diperoleh yaitu 20°C dengan menghasilkan rejeksi Gd-DTPA sebesar 99,73 % dan Sm-DTPA sebesar 99,58 %. Kata kunci: Gd-DTPA, Sm-DTPA, nanofiltrasi Abstract: Nowadays has been done research on the separation of rare earths as an important role in the development of technology. The separation and purification of rare earths is very difficult, because of the rare earth elements have similar properties with each other. Therefore, it is necessary to develop methods of separation and purification of rare earths from minerals, one of them is nanofiltration membrane with the addition of ligand Diethylene triaminepentaacetat (DTPA). This study aims to separate gadolinium(III) and samarium(III) by using nanofiltration membranes. The method used in this research
