In the present paper, we report the results of our investigation concerning the effect of concurrent ball milling on the cementation of copper by aluminum powder with the aim …
Microscale zero-valent aluminum (mZVAl), an excellent electron donor, presents great potential in the field of water treatment. However, surface inherent oxide film impedes its …
In this study, aluminum sulfate 18-hydrate [Al 2 (SO 4) 3 ·18H 2 O] particles of different sizes, which were obtained via high-energy ball-milling technology, were successfully …
Mechanical activation of anhydrous aluminum sulfate was performed in a planetary ball mill using hardened chromium steel vials and balls under air atmosphere. Milling was …
Despite a great thermodynamic driving force, copper cementation by aluminum from sulfate solutions involves a relatively slow kinetics due to the presence of the passive oxide …
Novel Fe-Al-SiO2 (FAS) poly-coagulants were prepared by the ball milling method using ferrous sulfate, aluminum sulfate, hydrophobic silica, and sodium carbonate as raw materials.
The cementation experiments were carried out in a polyamide jar with alumina balls inside by planetary ball milling. The studied parameters were ball number (0, 4), temperature (25-55 °C) …
High-energy ball milling is a promising approach to enhance the reactivity of mZVAl. In this study, taking nontoxic and biodegradable stearic acid (SA) as the process control agent (PCA), ball milled mZVAl (termed as mZVAl bm) was prepared and employed to activate …
The effects of ball milling on hydrous and anhydrous potash alum (potassium aluminum sulfate dodecahydrate, KAl(SO 4) 2 ･ 12H 2 O) were investigated by powder X-ray diffraction (XRD), Raman spectroscopy, and …
Here we show that the ball milling pretreatment could markedly facilitate the conversion of microcrystalline cellulose to HMF by titanyl sulfate (TiOSO 4). The ball milling pretreatment remarkably decreases the degree of crystallinity of …
