  • Aqueous Cr(VI) removal by a novel ball milled Fe0-biochar

    Oct 04, 2019 · A novel ball milled Fe0-biochar composite was synthesized by ball milling the mixture of biochar (pyrolyzed at 300 °C, 500 °C, and 700 °C) and micron grade iron powder. FTIR, SEM, TEM-EDS, XRD, and XPS were applied to characterize this composite. XRD results showed that iron carbide phase was formed during the ball milling process.

The product was washed four Stereoselective addition of nitromethane to conjugated en‐ynones was performed through the application of chiral squaramides. Three non‐classical approaches to promote the addition reaction were tested, including activation of the nucleophile by inorganic base in a biphasic aqueous system, thermal activation, and ball‐milling.

  • Ball milling a green technology for the preparation and

    Ball milling in aqueous conditions was also employed by the Wang group to obtain cellulose nanofibers from wood pulp. 49 In particular, they first treated dried the soft wood pulp in water at room temperature to loosen the hydrogen bonding between the fibres, then they milled the resulting loosened fibres in aqueous We used vibratory ball-milling of cellulose for varying periods of time to generate samples with different degrees of crystallinity. Hydrolysis with hydrochloric acid confirmed that progressive ball-milling resulted in higher rate of depolymerisation to glucose, consistent with the decrease in crystallinity.

  • Effects of ball milling on the physicochemical and

    Ball milling increased only the external surface area of low temperature biochars, but still dramatically enhanced their ability to sorb aqueous Ni(II). For higher temperature biochars with relatively low surface area, ball milling increased both external and internal surface area. The in situ formation of nanostructured aluminum hydroxides on the surface of alumina particles, which can work as inorganic binder, was reported in this paper. The effect of the suspension pH during milling of alumina powder and subsequent hydrothermal treatment for the hydroxide formation and microstructure was depicted. Under acidic pH condition, the formation of hydroxides was not observed.

    An inorganic sodium hydroxide aqueous solution was developed for the dissolution of ball-milled softwood. Extractive-free Masson pine powder was prepared from the wood meal by planetary ball milling for various lengths of time. The effects of ball milling on the dissolution and regeneration of Masson pine powder were investigated. In this work, a novel composite, ball-milled biochar (BMB) encapsulated in calcium-alginate (CA) beads (CA-BMB), was synthesized as an alternative adsorbent for the removal of methylene blue () from an aqueous solution.

  • THE BALL MILLING EFFECT ON TRIBASIC CALCIUM

    Ball milling The mechanical milling was carried out with a high energy ball mill (Spex 8000). TCP samples were milled for different periods 0, 5, 10 and 15 h to obtain TCP, TCP-5, TCP-10 and TCP-15 samples, respectively. The tribasic calcium phosphate powder was placed into a cess by ball milling is conducted for more than 2h. Due to these reasons, it is rather difficult to obtain stable and concentrated aqueous MAS suspensions to be used in the near-net shape forming of ceramics following colloidal pro-cessing techniques. In fact, near-net-shaping is of great importance because expensive post-sintering machining
