Settling of copper-rich suspended particles from acid drainage neutralization as a function of chemical composition and particle size distribution
(2022)
The attenuation of total and dissolved metals from acid drainage (AD) results from the interaction of physical andchemical processes occurring during and after AD neutralization in impacted rivers. Chemical removal occurswhen ...
Effect of particle size on copper removal by layered double hydroxides
(Elsevier Science Sa, 2016-06-03)
Layered double hydroxides are increasingly studied as heavy metal scavengers but the effect of particle size in their removal behavior has not been explored yet. Here, these aspects were studied in three solids with similar ...
Magnetic properties of acicular ultrafine iron particles
(Institute of Electrical and Electronics Engineers (IEEE), 2002-09-01)
Magnetic properties of acicular (similar to60 and similar to200 nm) iron particles, obtained by reduction of alumina-coated goethite particles, are reported. X-ray diffraction and Mossbauer spectroscopy showed that the ...
Effect of the relationship between particle size, inter-particle distance, and metal loading of carbon supported fuel cell catalysts on their catalytic activity
(SPRINGERDORDRECHT, 2012)
The effect of the relationship between particle size (d), inter-particle distance (x(i)), and metal loading (y) of carbon supported fuel cell Pt or PtRu catalysts on their catalytic activity, based on the optimum d (2.5-3 ...

Sediment grain size distribution and heavy metals determination in a dam on the Parana River at Ilha Solteira, Brazil
(Taylor & Francis Inc, 2009-07-15)
This paper reports on a preliminary evaluation of the grain size distribution of cadmium, lead and copper in sediment from Catarina Beach, Ilha Solteira, in the state of São Paulo, Brazil. Surface sediments were fractionated ...

Antimicrobial polymer composites with copper micro- and nanoparticles: Effect of particle size and polymer matrix
(SAGE, 2015)
The addition of metal particles, for instance, silver or copper, into polymer matrices is a relevant strategy producing novel antimicrobial materials. By using two particles with diameters around 10nm and 45 mu m, and ...
