Efficient hydrolysis of cellulose into glucose over sulfonated polynaphthalene (SPN) and rapid determination of glucose using positive corona discharge ion mobility spectrometry

Abstract

Sulfonated polynaphthalene (SPN) was successfully developed as solid acid catalysts for the hydrolysis of cellulose into high yields of glucose. The catalytic results indicate that the solid acid exhibits excellent activity, selectivity and recyclability. In addition two simple, rapid, selective, precise and accurate methods for the determination of glucose and cellulose were developed. The first method was based on the direct ion mobility spectrometry (IMS) measurements of glucose in reaction solution. The second method was based on UV-visible spectrophotometry, measurement of absorbance at 286 nm for cellulose.
