Higher amount of aluminium (Al) is a general feature of acidic soils which limits crop productivity. Cyanobacteria are also found on acidic soils where they encounter Al toxicity which can affect paddy productivity directly (due to reduction in nitrogen fixation) and indirectly (due to reduction...

Hydrochloric acid leaching is a good way to extract aluminum from secondary aluminum dross (SAD). However, the leaching kinetics of this process is still unclear. This study investigated the leaching kinetics of aluminum extraction from SAD by using hydrochloric acid. Leaching test results showe...

Calcium aluminium oxide (Ca2Al2O5) was synthesized via solid state method by using calcium carbonate and alumina calcined at 900 °C. The synthesized catalyst was characterized by TGA, XRD, FTIR, SEM, and BET. The particle size analysis and basicity test were also conducted. The catalyst was use...

Characteristics of dynamically formed oxide layers in Al–Ca alloys containing up to 2.0 wt.% calcium, which are commonly used in manufacturing Alporas closed-cell aluminum foams, were investigated using field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TE...

In this study, experimental method containing hydrogen evolution test, electrochemical measurement, galvanostatic discharge test and morphology analysis combining with theoretical method containing quantum chemical calculation and Monte Carlo simulation are used to study the inhibition performan...

The influences of calcium content on thickening stage, dynamic oxidation and subsequent formation of cell walls in closed-cell aluminum foams were investigated by both precise thermodynamic and experimental studies. A novel technique was also used for the sample preparation, and the compendious ...

The urgent global need to develop sustainable energy conversion methods and to minimize green-house gas emissions has intensified interest in finding more efficient and non-polluting means for power generation. Thermoelectric materials directly convert heat into electricity which can be used for...

The speciation of inorganic Sb(III) and Sb(V) ions in aqueous solution was studied. The adsorption behavior of Sb(III) and Sb(V) ions were investigated as iodo and ammonium pyrollidine dithiocarbamate (APDC) complexes on a column filled with Amberlite XAD-8 resin. Sb(III) and Sb(V) ions were rec...

The present work deals with the removal of Cr(VI) from aqueous media by modified Amberlite XAD-4 (MAX-4) resin through the solid phase extraction method. Different parameters such as pH, dosage and temperature were optimized during the batch experiment. The experimental data were analyzed by Fre...

An aminated Amberlite XAD-resin as a solid phase extractant was tested for speciation of inorganic mercury, Hg(II) and methylmercury, MeHg(I) in water and fish tissue samples. It was found that Hg(II) and MeHg(I) ions could be simultaneously retained by a column filled with AAXAD-4 resin at pH 4...

As a part of technological evaluation of Eskisehir-Beylikahir thorium–Rare Earth Elements (REEs) ore of Turkey, a novel study investigating the extraction behaviours of light REEs for Cyanex 272 impregnated Amberlite XAD–7 resin was carried out. Solvent impregnated resin (SIR) was prepared by ...

Bisphenol-A (BPA) was removed from water solution using washed (WX7) and impregnated (IX7) Amberlite XAD-7 resin with Aliquat-336 (A336). 0.5 g (IX7-0.5) and 1 g (IX7-1) of A336 per g of WX7 were loaded on the resin. Characterization of prepared adsorbents was done by FTIR, FE-SEM, EDS, BET. Poi...

Levulinic acid (LA) from aqueous solutions was removed by using commercial adsorbent Amberlite XAD-4 (XAD-4). The equilibrium and kinetic studies were performed to investigate the effect of adsorbent amount (1 g to 3.5 g at 298 K, 308 K and 318 K), initial acid concentration (2 g·L− 1 to 4 g·L...

Adsorption of U(VI) from Egyptian crude phosphoric acid was studied using the modified Amberlite XAD-2 resin. Modification process was performed by soaking Amberlite XAD-2 resin in tri-butyl phosphate (TBP) and di-2-ethyl hexyl phosphoric acid (D2EHPA) for increasing its adsorption capacity via ...

Chromium and its compounds are of particular concern due to their toxicity. Thus, their removal is of great importance before discharging into the environment. In this research, chemically modified magnetic Amberlite XAD-7HP was synthesized using Fe(II) and Fe(III) ions (iron oxide coated Amberl...

Novel sensors based on carbon paste assorted with amberlite XAD-4 resin and silver-doped titanium dioxide/amberlite XAD-4 resin (Ag-TiO2/XAD) were designed and employed for sensitive detection of flufenamic acid (FFA).
