Pembuatan Silika High Grade Dari Fly Ash Sawit Dengan Proses Ekstraksi Dan Ca…

One alternative raw materials manufacture of high grade silica is using palm oil mill fly ash. This research aimed to study the effect of temperature process, time and the ratio mass of zeolite and obtain optimum conditions cation exchange process (Fe) in a solution of sodium silicate with raw material palm oil mill fly ash. Palm oil mill fly ash is heated using oven at 105° C for 24 hours. Th…
