Simultaneous determination of F~- and MFP~(2-) in toothpaste by Ion chromatography;

Eight species: fluoride, chloride, sorbic acid, sulfate, phosphate, monofluorophosphate, glycerophosphate, and saccharin were analyzed by means of ion chromatography (IC) using a gradient elution with KOH as mobile phase, IonPac AS11 as the separation column, and suppressed conductivity detection.

A cationic photoinitiator 4,4′-diacetamidodiphenyliodonium hexafluorophosphate,which has not been reported yet,was synthesized from acetanilide and sulfuric acid in solvent acetic acid.

It is reported in this paper that femtosecond laser induced phosphorescence in Mn 2+ doped alumino-phosphofluoride glass and a new phenomenon of 365 nm UV light stimulated phosphorescence in femtosecond laser irradiated alumino-phosphofluoride glass after the femtosecond laser induced phosphorescence decayed completely.
