Journal ArticleDOI
Competitive adsorption of phosphate and arsenate on goethite.
Zhao Hongshao,Robert Stanforth +1 more
TL;DR: The results suggest a two-phase reaction on the surface, with the first phase being a rapid surface complex formation on the goethite surface, followed by the slower buildup of a surface precipitate on the adsorbed layer.
Journal ArticleDOI
Distinguishing adsorption and surface precipitation of phosphate on goethite (α-FeOOH).
Li Li,Robert Stanforth +1 more
TL;DR: In this article, a method for distinguishing between the two processes based on the change in zeta potential with increasing adsorption was presented, where the transition point from ad-sorption to surface precipitation was determined by using surface coverages.
Journal ArticleDOI
Evidence for surface precipitation of phosphate on goethite.
Adeline Ler,Robert Stanforth +1 more
TL;DR: The slow increase in xi-potential over time indicates that long-term reactions are occurring on the goethite surface, most likely involving the dissolution ofGoethite to release iron and the subsequent reaction between the iron and surface-bound phosphate.
Journal ArticleDOI
Integrated hydrometallurgical process for production of zinc from electric arc furnace dust in alkaline medium.
Zhao Youcai,Robert Stanforth +1 more
TL;DR: A novel and integrated hydrometallurgical process for the production of zinc powder from electric arc furnace (EAF) dust in alkaline medium is reported, finding that 38% of zinc and 68% of lead could be extracted from the dust when leached directly in caustic soda solution.
Journal ArticleDOI
Slow Adsorption Reaction between Arsenic Species and Goethite (α-FeOOH): Diffusion or Heterogeneous Surface Reaction Control
Junshe Zhang,Robert Stanforth +1 more
TL;DR: DMA desorbed completely and rapidly when the pH was raised, in contrast to the slow adsorption kinetics, indicating that the slow Adsorption step is not due to intraparticle diffusion.
