Abstract

The objective of this research was to study the effect of ash-solvent weight ratio and the number of crosscurrent in batch leaching of rice husk ash.
Ash of rice husk and distilled water put into a beaker glass, stirred well during 5 minutes (assume equilibrium). After that, the mixture was filtered by Buchner funnel and vacuum pump perfectly. The volum of filtrate was measured, and also determined the content of alkali active by acid base titration. The residue was added by 1000 ml fresh distilled water, mixed well and filtered again. The batch leaching operation on residue was repeated until 5 times.
Distilled water is good solvent for leaching of rice husk ash. The ash extract of rice husk contains potassium 84.7969 mg/L, silica 0.8255 mg/L, Carbonat 12.2 mg/L, sodium 38.075 mg/L, and magnesium 5.0006 mg/L.

Keywords : ash extract, crosscurrent, leaching, ricehusk.
