Future large-scale production of H2 for use as a clean fuel will likely depend upon gasifying coal or biomass followed by steam reforming the resulting gas mixture and separating the CO2 byproduct. The process of steam reforming and CO2 separation can be greatly simplified by utilizing a new material that combines a reforming catalyst with a sorbent for CO2. Such a material was prepared in the ...

Batch sorption experiments using a starch-based sorbent were carried out for the removal of heavy metals present in industrial water discharges. The influence of contact time, mass of sorbent and pollutant load was investigated. Pollutant removal was dependent on the mass of sorbent and contact time, but independent of the contaminant load. The process was uniform, rapid and efficient. Sorption...

In order to reduce the impact of eutrophication caused by agricultural residues (i.e., excess nitrate) in aqueous solution, economic and effective anionic sorbents are required. In this article, we prepared anionic sorbent using wheat straw. Its structural characteristics and adsorption properties for nitrate removal from aqueous solution were investigated. The results indicate that the yield o...

A molecularly imprinted silica gel sorbent for selective removal of 2-Hydroxybenzoic acid (2-HA) was prepared by a surface imprinting technique with a sol-gel process. The 2-HA molecularly imprinted silica gel (2-HA-MISG) sorbent was evaluated by various parameters, including the influence of pH, static, kinetic adsorption and selectivity experiments. The optimum adsorption capacity to the 2-HA...

Halloysite sorbent was added to liquid urine (dose 10 g/dm) and solid faeces (unmodified structure, dose 50 g/kg) being a subject of anaerobic fermentation in a hermetic system for 20 days. Identification of surface morphology and elementary chemical composition in microregions of the spent sorbent were done using scanning electron microscope Zeiss Supra 35 equipped with EDS detectors. Both gra...

The pure water contains 3% in the global. Human and manufacturing performances create release wastes having iron phosphorous metals into assets production them polluted dangerous human health environment. usual processes for elimination of metal ions those by chemical precipitation membrane filtration are very costly while purifying huge concentrations water, ineffective at lower amounts produc...

Alginate blended with cellulose nanocrystals (CNC), nanofibers (CNF), and tri-carboxylate (TPC-CNF) prepared encapsulated in the form of microcapsules (bio-polymeric beads). The cellulosic nanomaterials that used this study were investigated as for wastewater treatment applications. Batch experiments performed to removal copper, lead, magnesium, iron from aqueous solutions by beads. effects sor...

Abstract The removal of reactive blue 49 dye on a bio-sorbent material for Natural lemon peels(NLP) and Acid-activated carbon peels(AACLP) from aqueous solutions was studied. Preparation activated by Calcinations at temperature (300°C) one hour chemical activation phosphoric acid. Study different parameter such as effect contact time, adsorbent dose, pH solution, solution Adsorption comparison ...

With the aim of investigating the effects of carbonaceous sorbent amendment on plant health and end point contaminant bioavailability, plant experiments were set up to grow maize (Zea mays) in soil contaminated with polycyclic aromatic hydrocarbons (PAHs) and metals. Maize and pine derived biochars, as well as a commercial grade activated carbon, were used as amendments. Plant growth characteri...

The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmu...
