Computer-assisted Gran titration procedure for strong acid determination
Technical Report
·
OSTI ID:6061047
An automated method for determining, by coulometric titration, small amounts of strong acid in the presence of weak acids is given. Essentially, a pH meter and a coulometer are coupled with a Tektronix 4052 mini-computer, and a two-step computer program then directs the titration and calculates the equivalence point by the method of Gran. A comparison of precision and accuracy of results for test solutions by manual and automated data reduction methods is presented. The method is being used successfully to analyze for the H/sup +/ content in ambient aerosol samples from aerometric field experiments, and can be used for cloud and rainwater samples as well. 3 references, 1 figure, 1 table.
