Mineral carbonation using alkaline wastes is an attractive approach to CO2 utilization. Owing the difference between waste and feedstock CO2, developing utilization technologies without purification pressurization a promising concept. This study investigated potential method for via direct aqueous of synthesized concrete fines under atmospheric pressure low concentration. The reaction with different solid-liquid ratios concentrations introduced was examined in detail. Under basic conditions,...
Mineral carbonation of alkaline wastes is a promising route for carbon dioxide (CO2) capture and utilization. An exploration the potential relatively inert important to develop mineral carbonation. Large amounts coal fly ash are generated from coal-fired power plants must be treated. A fundamental study circular indirect was proposed fly-ash leaching, calcium carbonate (CaCO3) precipitation, solution regeneration with bipolar membrane electrodialysis (BPED) stages were investigated. In...
Ferronickel (FeNi) slag, as the main solid byproduct of FeNi industry, has potential to be utilized other than roadbed material. To broaden applications slag (such CO2-capturing materials), there is a need for treatment that breaks magnesium silicate bonds and transforms into MgO. As an initial study, this research treated by using sodium hydroxide followed water-washing. The present authors evaluated several alkali variables; such temperature (523 K 773 K), time (1–8 h), mass ratio between...
Abstract Electrolytic processes are widely used to synthesize different nanomaterials and it does not depend on what kind of the method has been applied (wet-chemistry, sonochemistry, plasma chemistry, electrolysis so on). Generally, reactions in electrolyte considered be reduction/oxidation (REDOX) between chemical reagents or deposition matter electrodes, line with Faraday’s law. Due presence electroconductive additives any electrolyte, polarization effect polar molecules conducting an...
Aqueous solubility (Sw), 1-octanol/water partition coefficient (Kow), and vapor pressure of the nonionic form 2,2',6,6'-tetrabromo-4,4'-isopropylidenediphenol (tetrabromobisphenol A or TBBP-A) were measured. From this, enthalpies solution vaporization estimated. Furthermore, enthalpy fusion melting point measured to estimate subcooled liquid pressure, infinite dilution activity coefficient, Henry's law constant. Since TBBP-A is expected exit in both ionic forms at near neutral pH, pH effects...
In recent years, while Cu production has increased, ore quality degraded.Consequently, copper smelting industries generate large amounts of byproducts and wastes, including slag.However, the use these wastes involve high costs most are discarded in landfills after processing.In some cases, contain valuable components, which may be profitable to recover.In other toxic or hazardous chemicals required treatment prevent their release.Therefore, processing is a significant activity, determines...
The solubility of scorodite synthesized in a novel atmospheric process was investigated. Stable (FeAsO4·2H2O) particles were produced by introducing oxidizing gas into reaction mixture containing ferrous sulfate and high-concentration arsenic (V) to convert ion ferric ion. obtained crystals released very low, almost negligible concentration the pH range 3 6, suggesting its long-term stability. thermodynamic parameters for dissolution scorodite, Ksp ΔGf, similar those reported previously....
