Hexafluorosilicate in the presence of standard anions
AN-S-277
pt_PT
<p>Determination of fluoride, chloride, nitrate, phosphate, sulfate, silicate, and hexafluorosilicate (calculated) using anion chromatography with conductivity detection after chemical suppression and subsequent UV/VIS detection with post-column reaction (see AN U-48). Hexafluorosilicate is hydrolyzed into fluoride and silicate. Both anion concentrations can be used for the calculation of the SiF<sub>6</sub><sup>2-</sup> concentration.</p>
