Weathered basalt activated at 950 ⁰C for 3h was used, for the first time, as a source of Fe(III) to prepare magnetic Fe 3 O 4 nanoparticles (MNPs). The synthesized Fe 3 O 4 MNPs were characterized by XRD, FTIR, FESEM, and TEM and utilized as a cost effective adsorbent for the removal of crystal violet (CV) dye at pH 7.0 and 25, 40, and 50 °C. The experimental data were fitted to the ...

Basalt - Igneous rocks

Basalt is a major rock type that occurs in virtually every tectonic setting. Basalt is clearly the most common volcanic rock on Earth and basaltic rocks (including gabbro, diabase and their metamorphosed equivalents) are the most common rocks in the crust 2.Basalt is also common on the Moon and other rocky planets of the Solar System.
