Modifikasi Permukaan Ca-Bentonite Sebagai Karier Imobilisasi Bakteri

Anita Valerie Stephani Simanjuntak, Dian Andriani, Muh Ade Artasasta

Abstract


Bentonit merupakan salah satu jenis mineral yang keberadaannya melimpah, namun belum dimanfaatkan secara optimal. Dengan meningkatkan pemanfaatannya, bentonit dapat dijadikan sebagai karier imobilisasi bakteri untuk meningkatkan efisiensi bioremediasi limbah. Peningkatan ini dapat dilakukan dengan memodifikasi permukaan Ca-bentonit dengan perlakuan asam, termal, dan surfaktan. Modifikasi Ca-bentonit dilakukan dengan pemberian asam larutan HCl 10%, pemanasan dengan suhu 100°C, serta pemberian surfaktan PEG 400 konsentrasi 20% w/v dengan waktu kontak 40 menit. Ca-Bentonit yang sudah termodifikasi kemudian di karakterisasi dengan SEM-EDS, FTIR, XRD, dan BET-BJH. Hasil menunjukkan bahwa modifikasi Ca-bentonit dengan menggunakan asam, termal, dan surfaktan dapat meningkatkan luas permukaan spesifik Ca-bentonit dari 109.2536 m2/g menjadi 115.9303 m2/g.
