The isolation process of alkali lignin (AL) from the valonea of Quercus variabilis Blume was optimized (liquid/solid ratio, 12.21; isolation time, 4.21h; isolation temperature, 42.21°C; and alkali concentration, 0.85mol/L) using the response surface method (RSM), with the highest isolation rate obtained being 22.67%. Then, the apparent structures of AL, enzymatic hydrolysis lignin (CEL) and milled wood lignin (MWL) were studied by scanning electron microscopy (SEM), which indicated that the… CONTINUE READING
