Resumo |
The limits of detection (3<i>s</i>) for ascorbic acid were 5×10<sup>−8</sup> M with acidic potassium permanganate using both flow injection analysis (FIA) and sequential injection analysis (SIA) whereas the soluble manganese(IV) afforded 1×10<sup>−8</sup> M and 5×10<sup>−9</sup> M for FIA and SIA, respectively. Determinations of ascorbic acid in Vitamin C tablets were achieved with minimal sample pretreatment using a standard additions calibration and gave good agreement with those of iodimetric titration. |
