“…Amperometric titrations of mercury(II) with thiocarbohydrazide (44) and with potassium bis(carboxymethyl)dithiocarbamate (246) have been reported. Bipotentiometric indication at mercury electrodes has been used in the successive coulometric determination of praseodymium and ytterbium (219). EDTA that is generated at a mercury pool cathode titrates both elements.…”

“…Experimental conditions have been given for the amperometric and bipotentiometric titration of mercury® with EDTA or with several related compounds (209). Electrogeneration first of EDTA and then of mercury(II) has been used in the successive determination of praseodymium and ytterbium (219). The amperometric titration with EDTA of mercury(II) in Me2SO has been studied (81).…”

This survey covers the period from the previous review (229) through Oct 1983. The order of treatment is the same as in that review. Unless otherwise specified, potentials are with respect to the saturated calomel electrode (SCE).Reviews of amperometric methods include drug analysis (120), the monitoring of the composition of alloys (177), and the determination of the platinum metals ( 56). An examination of the effect of the rate of amperometric titration on the position of the equivalence point has led to the conclusion that this rate can be increased without a marked decrease in accuracy (41). Other reviews concern oscillopolarographic (69,
