Adequate Method

This work describes an adequate method for the stabilization of three forms of sulfur (ionic, saturated, and unsaturated), with different chemical modifiers (Zr, Pd and Ca) during sulfur measurement as carbon monosulfide (CS) by high-resolution continuum source graphite furnace molecular absorption spectrometry.
