Product Description
11. When studying the dependence of the antimony peak on the accumulation time for concentrations of 4 ∙ 10-6 mol/l, the following data were obtained:
t, min 3 7 10 14 18
I, μA 15.4 36.0 50.9 72.0 92.8
From a 0.55 g sample of the mineral, after dissolving in 100 ml of acid and with an accumulation time of 12 min, a peak was obtained at 45.6 μA. Determine the content of antimony in the mineral (in %).
