摘要
A brief review of known mechanisms for formation of PCDD/Fs is presented. In this study, various lignin preparations and low molecular weight phenols that can be derived from lignin were chlorinated with or without unbleached pulp present to gain information on the formation of chlorinated dioxins and furans during pulp bleaching. Chlorination of lignin produced results similar to chlorination of unbleached pulp in terms of amounts of TCDD/Fs and isomer patterns. Spiking pulp with guaiacol (2-methoxyphenol), 2,4,5-trichlorophenol, and 4,5-dichlorocatechol all increased the levels of chlorinated dioxins, but suppressed formation of the furans. Coupling of chlorophenols does not appear to be a major pathway for formation of the 2378-TCDD and 2378-TCDF during pulp bleaching. © 1990.
