Spent pickling liquors contain high concentrations of heavy metals (titanium) and toxic fluoride ions. Waste streams must undergo chemical precipitation using hydrated lime ( ) to precipitate calcium fluoride ( CaF2cap C a cap F sub 2 ) sludge before water discharge.
Could you clarify the context? For example: titanbeizen
A final rinse in high-purity deionized water to prevent water spots and mineral residue formation. Spent pickling liquors contain high concentrations of heavy
(titanium pickling) is a critical chemical surface treatment used to remove oxides, scale, alpha-case layers, and contaminants from titanium and its alloys. Why Titanium Requires Pickling Titanium naturally forms a tenacious oxide layer ( TiO2cap T i cap O sub 2 titanbeizen
