Ly. Kheifets et al., USE OF DIFFERENTIAL CHRONOAMPEROMETRY FOR DETERMINING IONIC METAL SPECIES IN NATURAL-WATERS, Journal of analytical chemistry, 51(9), 1996, pp. 924-926
It is suggested that the previously revealed effect of Cr3+ ions on sp
ecies of other metals occurring in river waters be used for determinin
g ionic species of metals in river waters.
