Reactive oxygen species (ROS) such as singlet oxygen ((1)O(2)), superoxide (O(2)(-)), hydroxyl radicals (OH(*)), or hypochlorite ion (OCl(-)), can remove both hemicellulose and lignin from lignocellulose. Ox-B (US Patent 6,866,870), an ROS producing solution containing sodium hypochlorite and hydrogen peroxide, was investigated for its ability to oxidize(More)
