molybdate and carrier (H2SO4, 0.7 mol L1) flow rates and concentrations were selected in order not to dilute the sample too much
and to obtain conditions (pH, reagent concentration) necessary for
the reaction completion.
Volumes of injection loop (for oxalic acid) and mixing chamber
were chosen in order to obtain peak with characteristic plateau A2
(corresponding to the signal of molybdosilicic acid, Fig. 2) in
relatively wide an
