摘要: Iodimetric titrations with piezoelectric monitoring were based on the sensitive response of frequency to adsorption iodine electrodes a crystal. The differential shift-volume curve was used locate end-point. This technique determine 1 × 10−5 mol l−1 levels thiosulphate, thiocyanate and ascorbic acid.
