摘要：
The commercial bleaching trial of mixed colored wastepaper by thiourea dioxide (TD) was introduced. The bleaching parameters, sequence and other conditions were mainly studied, and the cost of TD bleaching was also discussed briefly. The trial results indicate that TD is an effective and highly competitive bleaching agent, particular for leaching and decolorizing of mixed colored wastepaper with a portion of mass-dyed wastepaper.
