摘要：

A new method, electrodeposition frequency shift titrimetry, is suggested, in which a piezoelectric crystal sensor is used as an end-point detector, based on its extremely sensitive response to changes in mass loading on its surface. This method is more sensitive than the frequency-metric titrations based on the change in conductance and it has a higher selectivity, controlled by the applied potential. Aqueous cyanide was detected by this method. (C) 1995 Academic Press, Inc.
