Pembuatan Silika High Grade Dari Fly Ash Sawit Dengan Proses Ekstraksi Dan Cation Exchange

---

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. Then fly ash reacted with 1,4N NaOH solution at 105° C for 50 minutes. Then obtained sodium silicate solution is reacted with Na-zeolite under the conditions obtained by the response surface methodology that is the contact time (40 minutes; 80 minutes), the ratio between the mass of the zeolite with a solution of sodium silicate (3:50; 7:50 ) (g/ml), temperature (40° C; 60° C). The analysis shows that the optimum condition cation exchange process is at temperature of 54° C for 26 minutes contact time with a mass number of Na-zeolite is used as much as 7.75 gram and % absorbed by 98.82%. The results of the optimization then precipitated using 10% H2SO4 and derived solid silica. XRF analysis results showed solid silica has a purity of 96.129%.
