Abstract

Penelitian ini bertujuan untuk menganalisa pengaruh efektifitas leaching dalam menghasilkan silika, dan menganalisa pengaruh penambahan senyawa template OA (Octyl Amine) pada pembentukan mesopori silika nanopartikel. Penelitian ini menggunakan bahan dasar sekam padi yang di leaching menggunakan asam kuat yaitu HNO3, HCl, dan H2SO4. Berdasarkan hasil pengujian EDX kadar silika yang paling tinggi dihasilkan pada leaching menggunakan HNO3 sebesar 39.21 (wt%). Gugus fungsi hasil FTIR menjelaskan adanya gugus siloksan. Hasil XRD menunjukkan bahwa silika mesopori silika nanopartikel hasil proses ekstraksi mempunyai fasa amorfus. Hasil SEM pada mesopori silika nanopartikel memiliki bentuk partikel yang lebih kecil dan penyebarannya merata. Dari hasil TEM didapatkan ukuran partikel pada mesopori silika nanopartikel berkisar antara 16-80nm. Mesopori silika nanopartikel memiliki diameter pori rata-rata sebesar 12.6 nm. Penggunaan OA berhasil untuk menyeragamkan ukuran partikel. ============ This research’s aims to analyse the effect of leaching effectiveness in generating silica, and to analyze the effect of addition of OA (Octyl Amine) template compound on mesoporous silica nanoparticle Hollow formation This research uses rice husk base ingredients in leaching using strong acids ie HNO3, HCl, and H2SO4. Based on the results of EDX testing the highest silica content was generated on leaching using HNO3 of 39.21 (wt%). The functional group of FTIR results explains the presence of siloxane groups. The XRD results show that the silica and mesoporous silica nanoparticles produced by the extraction process have an amorphous phase. The SEM results on the mesoporous silica nanoparticles have smaller particle shapes and the spread is evenly distributed. From the TEM results obtained particle size on mesoporous silica nanoparticles ranged between 16 nm-80 nm. Mesoporous silica nanoparticles have an average pore diameter of 12.6 nm. The use of OA works to uniform the particle size.
