  Ball milling coupled cascade magnetic separation to recover …

  202461 · Due to the lack of effective reduction and recycling methods, copper smelting slags (CSS) containing a large number of valuable metals are stockpiled. This work proposed a novel strategy of ball milling coupled cascade magnetic separation to achieve recovery of magnetite and ferrite and enrichment of Cu and Zn in alkali disaggregation …

  Improved charge separation via Fe-doping of copper …

  2015310 · In this paper, we explore the photoelectrochemical performance of CuWO 4 photoanodes for solar water splitting, and find that charge separation is the dominant limitation for this material. As a result, we attempt to dope the material with Fe, the first such example of doping this semiconductor for PEC water splitting.

  Fabrication of Bioinspired Structured Superhydrophobic and ...

  201771 · The development of effective and cheap oil/water separation materials is urgent for treating this problem. Herein, inspired by superhydrophobic typical plant leaves such as lotus, red rose and marigold, superhydrophobic and superoleophilic copper mesh was fabricated by etching and then surface modification with 1-dodecanethiol (HS (CH 2) …

  Preparation of Cu(II)-Imprinted Smart Microgels for Selective ...

  201564 · In this study, we demonstrate a new kind of surface imprinted smart polymer by using methacrylic acid (MAA) as function monomer, attapulgite as the support material, ethylene glycol dimethacrylate (EGDMA) as a crosslinker, and 2, 2’-azobisisobutyronitrile (AIBN) as initiator to prepare Cu (II)-imprinted microgels. The results showed that the …

  Enhanced adsorption of citric acid at the calcite surface by …

  2023420 · Highlights • Citric acid has weak depression on calcite. • The synergistic mechanism at solid-liquid interface was revealed. • Copper ions increase the depression of citric acid on calcite. • Copper ions and citric acid was selective co-adsorbed on the surface of calcite. • Flotation separation of scheelite from calcite was achieved using Cu 2+ /CA.

  Separation and preconcentration of trace quantities of copper …

  20111123 · We report on a sensitive, reliable and relatively fast method for separation, preconcentration and determination of trace quantities of copper(II) ion. It is making use of nanometer-sized γ-alumina nanoparticles modified with sodium dodecyl sulfate (SDS). The adsorptive potential was assessed via a Langmuir isotherm and the maximal sorption …

  Copper drives prion protein phase separation and modulates …

  2023113 · Prion diseases are characterized by prion protein (PrP) transmissible aggregation and neurodegeneration, which has been linked to oxidative stress. The physiological function of PrP seems related to sequestering of redox-active Cu 2+, and Cu 2+ dyshomeostasis is observed in prion disease brain. It is unclear whether Cu 2+ …
