Arsenazo HI was applied in the determination of thorium in biological materials [103,104], natural waters [34,105,106], fertilizers [107], glass [108], silicate minerals [2,10,27,55,109], niobium and tantalum minerals [110], uranium minerals [3,18], manganese ores [19], lanthanide compounds [26,44], zirconium minerals [111], titanium concentrates [111], ilmenite and rutile [112]. Thorium was determined in waters with the use of the FIA technique [106]. 

In general, only low-carbon steel (5)y niobium, tantalum, and molybdenum are desirable materials of construction for molten lithium. Molten lithium will attack quartz, glass, and silicates in general, and the lithium oxide often present in molten lithium at high temperatures is an excellent flux for most oxides and silicates.
