Journal ArticleDOI
Biosorption of metals in brown seaweed biomass
TL;DR: In this article, the feasibility of pre-treatment of brown seaweeds to develop a better biosorbent was evaluated by its performance, the degree of its component leaching (measured by the weight loss and TOC) as well as by the number of ion-exchange sites remaining in the biomass after the pretreatment.
Journal ArticleDOI
A comparison of TEM and DLS methods to characterize size distribution of ceramic nanoparticles
TL;DR: In this article, the accuracy of dynamic light scattering (DLS) measurements compared with transmission electron microscopy (TEM) studies for characterization of size distributions of ceramic nanoparticles was compared.
Journal ArticleDOI

TL;DR: X-ray absorption fine structure spectroscopy and density functional calculations were used to determine the structural model of arsenic surface complex on gibbsite mineral in this paper, which showed that As(V) forms an inner sphere bidentate binuclear complex on the surface of Al oxyhydroxyl octaedra.
Journal ArticleDOI
Adsorption and desorption of arsenic on an oxisol and its constituents
TL;DR: The results indicated that As(V) is mainly adsorbed as an inner sphere complex, and As(III) may be adsorbent as aninner or an outer neutral complex.
Journal ArticleDOI
Removal of As(III) and As(V) from water using a natural Fe and Mn enriched sample
TL;DR: The arsenic removal capacity of a natural oxide sample consisting basically of Mn-minerals, and Fe-oxides, collected in the Iron Quadrangle mineral province in Minas Gerais, Brazil, has been investigated and demonstrated the high adsorption capacity of the material.
