Método titrimétrico para determinar fosfito em amostras agroindustriais Titrimetric method for phosphite determination in agricultural chemical samples

<abstract language="eng">A new titrimetric method for the determination of phosphite in fertilizer samples, based on reaction of H3PO3 with standard iodine solution in neutral media, is proposed. Diluted samples containing ca. 0.4% m/v P2O5 are heated and titrated with 0.05 mol L-1 i...
