Chlorine Dioxide Bleaching

Chlorine dioxide is an excellent bleaching chemical because it is very selective for lignin. Because of this, its use has expanded greatly over the last few decades. This course discusses the purpose of chlorine dioxide bleaching and the basics of chlorine dioxide bleaching chemistry. It also describes the equipment used in chlorine dioxide bleaching, as well as the typical ECF bleaching sequences such D0, D1, and D2 along with their differences.
