Equilibrium moisture content (EMC) as a function of relative humidity (RH) was measured in oriented strandboard. particleboard, medium-density fiberboard, hardboard, high pressure laminates, and solid wood. The measurements were made in both adsorption and desorption at 2 9 2 . The EMCRH data were fit to Nelson's sorption isotherm. It was found that Nelson's model can be used to describe the ex...

It is the purpose of this paper to investigate data fitting attributes exponential integral isotherm, which was first derived by Ruthven in 2004 describe adsorption at gas–solid interfaces. The a variant virial incorporates two parameters Langmuir isotherm and has an expandable mathematical structure. lain dormant for nearly 20 years. This fact may seem surprising considering versatility as wil...

This study investigates moisture uptake and diffusion mechanisms in thermoset particle-filled composites for anchor applications. Two epoxy-based with low inorganic filler content one vinyl ester-based high were studied. Material characterization revealed particle size distribution, density, the occurrence of pores, composition. Moisture was monitored at different temperatures, relative humidit...

ss as: Sa t bark. Abstract Biosorption of nickel ions from aqueous solutions by modified loquat bark waste (MLB) has been investigated in a batch biosorption process. The biosorbent MLB was characterized by FTIR analysis. The extent of biosorption of Ni(II) ions was found to be dependent on solution pH, initial nickel ions concentration, biosorbent dose, contact time, and temperature. The exper...

C-phycocyanin is a natural blue dye extracted from Spirulina platensis, which has many applications in the food and pharmaceutical industries. In this paper the effect of pH and temperature on the adsorption of C-phycocyanin onto two different ion exchange resins (Streamline DEAE and Streamline Q XL) for expanded bed adsorption chromatography was investigated. Moreover, the kinetics and adsorpt...

The preparation and testing of thiol-functionalised silica-coated magnetite nanoparticles (TF-SCMNPs) is described. The characteristics of these particles are assessed at different stages in the production process using X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier Transform Infrared Spectroscopy (FTIR), and a magnetometer. The particles were found to be almost spheri...

Biochar converted from agricultural residues or other carbon-rich wastes may provide new methods and materials for environmental management, particularly with respect to carbon sequestration and contaminant remediation. In this study, laboratory experiments were conducted to investigate the removal of phosphate from aqueous solution by biochar derived from anaerobically digested sugar beet tail...
