The Structural Changes of Alkaline Peroxide Mechanical Pulp Residual Lignin with Laccase-Mediator Treatment

Abstract:

In this paper the two-stage method of enzyme-mild acidic hydrolysis was adopted to isolate lignin from the APMP(Alkaline Peroxide Mechanical Pulp),then the isolated lignin was treated with a laccase-mediator system(LMS).The phosphor magnetic resonance spectrum (31P-NMR) measurements and Infrared spectral analysis technology were chosen to analyze the structural changes of LMS-treated APMP residual lignin.
