Biosorption using agricultural wastes has been proven as a low cost and efficient way for wastewater treatment. Herein, grape peel treated by microwave- and conventional-hydrothermal processes was used as low cost biosorbent to remove methylene blue (MB) from aqueous solutions. The adsorption parameters including the initial pH value, dosage of biosorbents, contact time, and initial MB concentr...
in this paper, indium tin oxide (ito) nanoparticles has been prepared by chemical methods under given conditions with solution of indium chloride (incl3·4h2o), tin chloride (sncl4·5h2o) in ammonia solution. the samples were characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem) analyses after heat treatments. the sem results showed that, the size of the ito particles pr...
One of the promising avenues for biomass processing is the use of water as a reaction medium for wet or aquatic biomass. This review focuses on the hydrothermal catalytic production of fuels and chemicals from aquatic biomass. Two different regimes for conversion of aquatic biomass in hydrothermal conditions are discussed in detail. The first is hydrothermal liquefaction, and the second is hydr...
Hydroxy davyne is a hydrated aluminosilicates with the same structure as cancrinite mineral group. Scientist categorized hydroxy davyne as zeolite because of its low temperature formation conditions and hydrated structure. Existence of [Ca.Cl] + group instead of [Na.H2O] + group is the significant property of this mineral. Alteration of volcanic ash in presence of alkaline hydrothermal solution...
