Adsorption Mechanism of Lead on Wood/Nano-Manganese Oxide Composite
Discharge of untreated industrial wastewater containing heavy metals such as Pb2+ is hazardous to the environment due to their high toxicity. This study reports on the adsorption, desorption, and kinetic study on Pb2+ removal from aqueous solutions using wood/Nano-manganese oxide composite (WB-NMO). The optimum pH, contact time and temperature for adsorption were found...
متن کاملI-17: The Mechanism of Gonadal Sex Determination
Background In mammals, a single exon gene SRY on the Y-chromosome is activated in the XY gonadal primordium and initiates a cascade of molecular and morphological events leading to testicular differentiation. SRY-encoded protein (SRY) is a transcription factor harboring a HMG-box DNAbinding motif that upregulates SOX9, which encodes another transcription factor sharing the DNA binding motif wit...
متن کاملNon-malignant respiratory diseases and occupational exposure to wood dust. Part I. Fresh wood and mixed wood industry.
This paper reviews associations in literature between exposure to wood dust from fresh wood and non-malignant respiratory diseases. Criteria for inclusion are epidemiological studies in English language journals with an internal or external control group describing relationships between wood dust exposure and respiratory diseases or symptoms. The papers took into account smoking, and when deali...
متن کاملAcetylation of wood – A review
Wood is a porous three dimensional, hydroscopic, viscoelastic, anisotropic bio-polymer composite composed of an interconnecting matrix of cellulose, hemicelluloses and lignin with minor amounts of inorganic elements and organic extractives. Some, but not all, of the cell wall polymer hydroxyl groups are accessible to moisture and these accessible hydroxyls form hydrogen bonds with water. As the...
متن کاملCapillary flooding of wood with microemulsions from Winsor I systems.
A new approach based on microemulsions formulated with at least 85% water and minority components consisting of oil (limonene) and surfactant (anionic and nonionic) is demonstrated for the first time to be effective for flooding wood's complex capillary structure. The formulation of the microemulsion was based on phase behavior scans of Surfactant-Oil-Water systems (SOWs) and the construction o...
