| Abstract: | Introduction Arsenic is a well known water contaminant that causes toxicological and carcinogenic effects. In this work magnetite nanoparticles
were examined as possible arsenic sorbents. The objective of this work was to develop a sorption kinetics model, which could
be used to predict the amount of arsenic adsorbed by magnetite nanoparticles in the presence of naturally occurring species
using a first-order rate equation, modified to include adsorption, described by a Langmuir isotherm. |
