Abstract
Penelitian ini bertujuan untuk meningkatkan stabilitas termal, kinerja fluks, dan rejeksi membran selulosa asetat dengan penambahan zeolit-A. Penambahan zeolit-A dilakukan sebanyak 6 variasi yaitu sebesar 0%, 5%, 10%, 15%, 20%, dan 25% dari persen total berat polimer. Membran dibuat dengan teknik inversi fasa rendam endap, kemudian digunakan untuk aplikasi pemisahan zat warna Congo red. Membran yang dihasilkan dikarakterisasi dengan SEM, TGA, FTIR, dan AFM. Hasil yang diperoleh menunjukkan bahwa penambahan zeolit-A sebanyak 20% pada membran selulosa asetat (SA/Z 20%) dapat meningkatkan stabilitas termal dari suhu 334,43 - 380 °C menjadi 337,65 - 400°C; fluks air membran dari 5,69 L/m? jam menjadi 378,17 L/m? jam, fluks zat warna dari 4,63 L/m? jam menjadi 230,35 L/m?.jam; dan nilai koefisien rejeksi dari 93,21% menjadi 98,92%.

This study aims to improve thermal stability, performance of flux and rejection cellulose acetate membranes by addition of zeolite-A. Zeolite-A was added in 6 variations, which are 0%, 5%, 10%, 15%, 20%, and 25% of the percent of polymer total weight. Membranes were prepared by phase inversion method, then were used in congo red textile dyes separation process. Membranes were characterized with SEM, TGA, FTIR, and AFM. Result showed that the addition of zeolite-A 20% can improve thermal stability from temperature 334,43°C — 380°C to 337,65°C - 400°C; pure water flux performance from 5,69 Lin’ h to 374,3 L/m?h: congo red flux from 4,63 L/im’.h to 230,35 L/m?.h; and rejection from 93,21% to 98,92%.
