Bj. Basu et al., DIFFERENTIAL-PULSE POLAROGRAPHIC-DETERMINATION OF TRACE LEVELS OF IRON(III) BY USING THE CATALYTIC CURRENT, Fresenius' journal of analytical chemistry, 349(6), 1994, pp. 477-478
Trace of iron(III) are determined by differential pulse polarography i
n a medium of sodium hydroxide and sodium bromate using the catalytic
current. Various cations do not interfere. The relative standard devia
tion is 2%.
