UOP 248-92: Alkalinity and Fluoride in Alkaline Solutions

�� FREE PREVIEW (First 5 Pages) ✔ First 5 pages free to download · No email required · Full document available after purchase This document, UOP 248-92, details a method for determining alkalinity and fluoride content in alkaline solutions, specifically those used for neutralizing hydrofluoric acid (HF) in pickling operations. The method involves a colorimetric titration to determine alkalinity and a potentiometric titration to determine fluoride concentration. The fluoride concentration is determined as a weight percentage of KOH used for neutralization, ranging from 0.016 to approximately 50 weight percent.
