Simultaneous determination of Mn2+ and Fe3+ as 4,4′[(4-cholorophenyl)methylene] bis(3-methyl-1-phenyl-1H-pyrazol-5-ol) complexes in some foods, vegetable and water samples by artificial neural networks

► Accurate methods for determinations of cations to maintain human health is necessary. ► Derivative bis pyrazole ligand used for the simultaneous determination of cations. ► The results show, the synthetic ligand is highly selective. ► Determination of cations was performed in rice and some vegetable samples by ANNs.
