A Highly Sensitive Multicommuted Flow Analysis Procedure for Photometric Determination of Molybdenum in Plant Materials without a Solvent Extraction Step

<div>Effect of the iron (III) concentration on sensitivity. Curves a and b are related with blank and a 150 <i>μ</i>g L<sup>−1</sup> Mo(VI) standard solution, respectively. Experimental conditions: 0.44 mol L<sup>−1</sup> SnCl<sub>2</sub>; blank and Mo (VI) standard solution in 1.5 mol L<sup>−1</sup> HC medium; 7 sampling cycles; sampling time intervals of 2.0 and 1.0 s for insertion sample and SCN<sup>−</sup> solution, respectively; pumping rate at 50 <i>μ</i>Ls<sup>−1</sup>.</div>
