Table 1. BET Surface Area and Crystallinity Index of Untreated and Pretreated RH at Optimal Conditions^a.

	surface area (m²/g)		degree of crystallinity (%)
biomass	native	pretreated	native	pretreated
rice husk	2.1	5.4	70.1	82.3

Optimal pretreatment conditions: 10% (w/v) RH in water/ethanol/MIBK (24%:32%:44%) using 3% H₃PO₄–AC for 1 h at a microwave power of 300 W.
