A little fluorine turns an insulating ceramic known as white graphene into a wide-bandgap semiconductor with magnetic properties. Rice University scientists said that could make the unique material su...
Simultaneous determinations of fluorine, chlorine, and sulfur in rock samples by ion chromatography combined with pyrohydrolysis
pyrohydrolysis halogen sulfur ion chromatography geological reference material
2017/4/10
We present a simplified method for simultaneous determinations of fluorine (F), chlorine (Cl), and sulfur (S) contents
and isotopic abundances in rock samples. After using pyrohydrolysis to extract F...
