摘要: A process for the manufacture of wood composite materials includes the steps of: preparation of a thermally curable resin by reacting a polycondensation-capable phenolic compound and/or an amino plastic forming agent with 5-hydroxymethylfurfural (HMF) under conditions leading to the formation of polycondensation products, bringing the resin into contact with lignocellulose-containing material, and curing the resin with formation of the wood composite material. The 5-hydroxymethylfurfural includes at least one HMF oligomer. Further, wood composite materials are obtainable by the process.

摘要: A cross-linked terpolymer (BSDF) obtained by polycondensation of bisphenol-S, formaldehyde and 1,6-diammohexane. The terpolymer is highly efficient in eliminating lead ions from aqueous solutions. The adsorption of lead ions on BSDF was studied under different conditions such as: pH, contact time and temperature. The adsorption kinetics fits Lagergren second order kinetic model that are in agreement with the low surface area as a chemisorption process. Applying BSDF on non-spiked and spiked real wastewater samples under optimum conditions revealed the high efficiency of BSDF in removing toxic metal ions.
