Title: GRAN METHOD OF ENDPOINT DETERMINATION IN CHLORIDE ANALYSIS BY POTENTIOMETRIC TITRATION
Accession Number: 00183522
Record Type: Component
Availability: Find a library where document is available Abstract: The Gran method of endpoint determination can replace the currently used first-derivative method in the potentiometric titration procedure for the analysis of chloride in hardened concrete. This modification improves the procedure by (a) circumventing the frequently encountered difficulty in endpoint determination that arises from unstable electrode potentials, (b) eliminating the need to spike solutions of low-chloride concrete samples with a known amount of chloride before titration, (c) enabling the titration to be performed more quickly, and (d) improving the overall precision and accuracy. /Author/
