Abstract
Silika dengan imobilisasi gugus amino dengan bahan dasar abu sekam padi telah dibuat melaluiproses sol-gel. Sebagai perbandingan, dibuat pula silika gel tanpa gugus organik.Larutan mendidih natriumsilikat (1,5 N) ditambahkan pada abu sekam padi, kemudian filtratnya dipisahkan sebagai larutan natriumsilikat. Selanjutnya , kedua filtrat digunakan untuk sintesis silika gel dengan dan tanpa gugus organik. 3-Aminopropiltrimetoksisilan (APTS) ditambahkan ke dalam larutan natrium silikat, dilanjutkan denganpenambahan asam klorida perlahan-lahan sampai pH 7 dan pH 3. Gel yang terbentuk diperam selama 18jam dengan temperatur 80oC, dicuci dengan air kemudian dikeringkan pada temperatur 80oC selama 9 jam.Silika gel dibuat dengan cara yang sama. Kedua produk dikarakterisasi dengan FTIR dan XRD, serta diujikemampuan adsorpsinya terhadap logam Ni(II). Hasil menunjukkan bahwa silika gel hasil mempunyai polayang sama dengan silika Kiesel Gel 60 dari Merck, baik spektra FTIR maupun defraktogram XRDnya,sedangkan bahan hibrida amino-silika mempunyai puncak-puncak serapan yang menunjukkan adanyagugus amin (-NH2) dan rantai alifatik (-CH2-) di samping kesamaan pola dengan silika standar. Dalam ujiadsorpsi, amino-silika mengadsorpsi Ni(II) lebih tinggi dibanding silika gel dengan kapasitas adsorpsimasing-masing 0, 106 mol/g adsorben dan 0,0088 mol/g adsorben.
