Stepwise MLR generated three models (five to nine independent variables) 2 2 with R values of 0.860 to 0.920. The three models showed high prediction performance, Q (0.922 to 0.948).

Lignocellulosic biomass has been identified as a suitable feedstock for future large-scale bio-refineries. Dissolution of lignocellulosic biomass by ionic liquid is by no means considered as a most facile method to disrupt the tight packing arrangement of cellulose fibrils in the crystalline domains of cellulose. The celluloses regenerated by rapid precipitation the dissolved cellulose dopes with an anti-solvent such as water have demonstrated a great improvement in term of enhancing enzymatic saccharification of cellulose. The saccharification yield ranged from 80 % to 90 % for the regenerated cellulose while only around 25 % could be achieved for the untreated cellulose due to the increment of surface area accessible to enzymes adsorption. 1 114 3rd ICYC 2010 Universiti Sains Malaysia ENV-P25 23rd-25th June 2010 SYNTHESIS AND CHARACTERIZATION OF COPPER -CONTAINING CARBON NANOTUBES (CNTs) AND THEIR USE IN THE REMOVAL OF IMPURITIE...
