Pengaruh Konsentrasi Pelarut Dan Rasio Padat-Cair Pada Ekstraksi Silika Dari Fly Ash (Abu Terbang) Batu Bara
Using coal in industrial and power plant always increase every year. Increasing
using of coal linearly with number of productrion waste of fly ash from coal. One
of alternative method for using fly ash as raw material of silicate. On this research
using some variable : solvent consentration (2, 2,5 and 3M) and ratio of solute –
liquid (1:6, 1:8 and 1:10). From the analysis of sample with using gravimetry
method acquired optimal condition on solvent consentration 3 M and ratio solute-
liquid 1:10 with silicate convertion 41,3%.
