Adsorbents of granular activated carbon doped with iron (Fe/GAC) were synthesized in the laboratory and their capacity for removal of arsenic species was measured by means of techniques of equilibrium adsorption and ...

The effect of biosolid incorporation on arsenic distribution in Mollisol soils in central Chile was studied. Two soils were sequentially extracted for arsenic with a five-step method that accounts for the following arsenic ...

Adsorption of As (V) by poly (N-octyl-4-vinylpyridinium) bromide (P4VPyC8), used as solid phase, was studied. Determination of As (V) was carried out by direct measurement of the fluorescence intensity on the solid phase. ...

Water arsenic reduction for human consumption represents a global environmental challenge, and there is a wide variety of methods for its removal. The aim of this study was to investigate the kinetics and equilibrium of ...

We present in this work a comprehensive investigation of the role played by dissolved tetrafluoroboric acid on the electrochemical response of a polycrystalline platinum electrode in acidic media. HBF(4) from two different ...

The objective of this work was to investigate the interaction of arsenic species (As(III) and As(V)) with tropical peat. Peat samples collected in Brazil were characterized using elemental analysis and C-13 NMR. Adsorption ...

The purpose of this research is to evaluate the aptitude of two residual soils for the remediation of groundwater contaminated by arsenic (As). Batch and soil column tests were performed to evaluate removal of As from ...
