A study of polymerization of aspen (Populus) wood lipophilic extractives by SEC and Py-GC/MS

Author: Sithole, Bishop B ; Lapierre, L ; Watanabe, C Date: Mar 2013 Studies have been conducted on the formation of polymerised wood resin in model compounds and in lipophilic extracts of aspen. Our studies indicate that polymerization of wood resin components occurs during seasoning of aspen wood. The ... Read more
Using Py-GC/MS to detect and measure silicone defoamers in pulp fibres and mill deposits

Author: Sithole, Bishop B ; Watanabe, C Date: Sep 2013 Defoamers are often used to control or reduce foam problems in a variety of pulp and papermaking processes. It has been recognised that non-judicious use of defoamers can lead to undesirable deposition problems. Amide-based defoamers have ... Read more
Using Py-GC/MS to fingerprint additives associated with paper mill effluent toxicity episodes

Author: Sithole, Bishop B ; Pimentel, J ; Gibbons, S ; Watanabe, C Date: Oct 2012 Understanding the cause of effluent toxicity is an important requirement for its prevention, remediation and return to compliance. One component of the strategy entails identification and fingerprinting of additives or components in additives ... Read more
