Abstract A multivariate chemometric method for monitoring the mass loss of Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) by IR spectroscopic determination chemical changes occurring during heat treatment (160 - 260 °C, 2 8 h) these wood materials was developed. The based on handling FTIR data treated untreated powder samples partial least squares (PLS) method. In addition, unknown (treated spruce) were classified into separate groups principal component analysis (PCA) in...
Abstract Hardwood (Betula pendula) chips were extracted having alkaline aqueous solutions with varying chemical charges (1, 2, 3, 4, 6, and 8% of NaOH on wood), treatment times (30, 60, 90, 120 minutes), temperatures (130°C 150°C). The total amount material removed was in the range 2.1–16.5% original dry feedstock. This fraction characterized terms carbohydrates their degradation products (mainly aliphatic carboxylic acids together some furanoic compounds), lignin, extractives. Low alkali...
European whitefish Coregonus lavaretus has increasingly become an important species for aquatic food production, especially in the Nordic countries. Whitefish is produced traditional cage and pond operations, recirculating aquaculture system (RAS) which, unfortunately, off-flavors odors, mostly caused by geosmin (GSM) 2-methylisoborneol (MIB), can accumulate fish flesh from circulating water. GSM MIB have very low human sensory detection limits and, therefore, often disliked consumers even...
Floc properties and dewatering of activated sludge from the pulp paper industry were studied prior to after an oxidative conditioning using Fenton's reagent Sludge samples taken four treatment plants, which differed with respect organic loadings wastewater source. Poor dewaterability was typical heavily loaded sludges a positive correlation between filtrability concentration exopolysaccharides observed. Oxidative improved all tested, but especially that sludges. Lab-scale piston press...
Abstract Modified wood fibres open new perspectives to create value-added products based on renewable raw materials. An interesting option is the targeted modification of fibre surfaces by oxidative enzymes. This two-stage functionalisation method consists enzymatic activation followed addition radicalised compounds reacting preferentially radical coupling. In this work, bleached and unbleached softwood TMPs with laccase isolated from Trametes hirsuta was studied. The formation stability...
