Point-of-use (POU) devices with satisfactory lead (Pb2+) removal performance are urgently
needed in response to recent outbreaks of lead contamination in drinking water. This study …

Metal ions are commonly used as activators to improve the anionic collector flotation of
oxide minerals with an accepted activation mechanism that the prior addition of metal ions …

The coordination chemistry of lead (II) in the oxygen donor solvents water, dimethylsulfoxide
(dmso, Me2SO), N, N-dimethylformamide (dmf), N, N-dimethylacetamide (dma), N, N …

The adsorption of hydrated heavy metals on graphene quantum dots is investigated using
the density functional theory. The considered heavy metals are Cd and Pb that are hexa …

Using microflotation experiments, this study investigated the effect of Pb 2+ ions on flotation
performance of cassiterite (SnO 2) by using benzohydroxamic acid (BHA) as collector …

Recycling treatment of wastewater containing hexavalent chromium [Cr (VI)] has always
been an important environmental issue. In this paper, taking advantage of the natural affinity …

The strategy of enhancing the surface activity by preadsorption of metal ions (surface
activation) is an effective way to promote the adsorption of surfactant on surfaces, which is …

Hydration and, in particular, the coordination number of a metal ion is of paramount
importance as it defines many of its (bio) physicochemical properties. It is not only essential …

Surface coordination chemistry is important in areas such as adsorption, separation, and
catalysts. In this work, surface coordination interactions of benzohydroxamic acid (BHA) with …

In natural environments, multiple metal ions are concomitant, and their adsorption at clay
mineral/water interfaces is competitive and selective. In this study, the competitive …
