Abstract
Practical and cost-effective uses for peroxymonosulfate can be developed in pulping and bleaching. Peroxymonosulfate pulping produces strong pulps, has lower capital requirements, and is less environmentally troublesome compared with current pulping processes. The cost of oxidant may, however, be somewhat too high for practical use. We discuss means for reducing the cost and for disposal or recovery of the spent treating liquors. Low-lignin chemical pulps were effectively bleached by alkaline solutions of peroxymonosulfate. Our results indicate that a practical bleaching sequence can probably be developed employing only peroxymonosulfate and oxygen as oxidizing agents.
