A large amount of wastewater containing organic components,including hemicellulose,pectin and lignin,is produced during the preparation of fibers from mulberry barks.In present study,the degumming waste liquid of mulberry bark fibers was used as the raw material to investigate the technology for efficiently isolating and recovering hemicellulose,pectin,lignin and other utilizable components and to characterize chemical structures of the recovered samples.The results showed that pH 4.5 of the waste liquid an...
