Pengaruh Waktu Dan Konsentrasi Polietilen Glikol Dalam Proses Presipitasi Sil…

Silica precipitation synthesis has been carried out from palm oil fly ash waste by using polyethylene glycol as dispersant. This study aims to determine the effect of time and concentration of polyethylene glycol (PEG) on yield and diameter size of silica primary particles on the silica precipitation process from POMFA. Silica is obtained by sodium silicate solution (Na2SiO3) added with PEG-400…
