Electrochemical removal of fluoride ions from industrial wastewater
TLDR
In this article, the fluoride ions were removed electrochemically from a solution using a combined electrocoagulation and electroflotation process, and the composition of the sludge produced from the operation was analyzed using X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometers (ToF-SIMS).About:
