“…The production of silica nanoparticles is anticipated to be non-toxic and economic in nature. An investigation on forming amorphous silica nanoparticles from rice husk (RH) biomass is studied for different applications (Kalapathy et al 2000;Carmona et al 2013;Wong et al 2014). However, finding the lucrative resources for large scale production of silica nanoparticles is still need to be refined as RH is also useful in animal feeds.…”

“…Nanopartikel merupakan partikel yang memiliki ukuran <100 nm. Nanopartikel silika memiliki beberapa keunggulan yaitu luas permukaan terhadap volume lebih besar, ketahanan panas yang baik, kekuatan mekanik yang tinggi dan inert sehingga digunakan sebagai prekursor katalis, absorben dan filter komposit [6]. Gambar 1. menunjukkan limbah pasir silika bekas inti cor.…”

“…Metode yang sederhana berdasarkan penggunaan larutan natrium silikat dan pencampuran dengan larutan asam dapat dikembangkan untuk mensintesis adsorben silika dari abu sekam padi dengan kontaminan mineral yang sedikit [5]. Apabila abu sekam padi diolah menjadi silika gel dengan metode sol-gel, maka permukaan silika dapat digunakan untuk menyerap suatu adsorbat.…”

“…pH dapat mempengaruhi muatan gugus-gugus fungsional dari permukaan silika termodifikasi APTS yang berperan aktif dalam proses penyerapan logam berat [5]. Demikian halnya perubahan pH dapat mempengaruhi proses adsorpsi, sehingga ion H + dapat bereaksi dengan gugus fungsi pada sisi aktif permukaan adsorben.…”
