Buchanan, B R

We were able to predict acid concentration to {plus minus}0.08M HNO{sub 3}. In the presence of Al{sup 3} interference, the prediction dropped to {plus minus}0.29 mols/liter over the range 0 to 9M HNO{sub 3}. Temperature affects the prediction of acid adversely and would have to be modelled out or the sample cell thermostated prior to using this method. 10 refs, 12 figs.(DLC)
