a method has been offered for the kinetic determination of trace mercury(Ⅱ) on the basis of the following catalytic reaction by mercury(Ⅱ) ion:[Fe(CN) 6] 4- +3 o phen[Fe( o phen) 3] 2+ +6CN -,and the sensitive response of piezoelectric quartz crystal (PQC) to the cyanide ion.The response mechanism of mercury(Ⅱ) ion to PQC sensor、response curve、the optimum conditions for the replacement reaction and the effects of the foreign ions have been studied.This method has been applied to the determination of mer...
