“…32,33 Considerando que o DTPA se assemelha muito aos aminoácidos presentes na seiva das plantas, parece razoável atribuir a baixa translocação de metais pesados, notadamente Pb, à formação de estruturas semelhantes nas plantas. .…”

“…DTPA is potentially an octadentate ligand, but typically forms less than 8 bonds with most metal cations, leaving one or two sites available for bonding with other reagents. [36,37] Hence this can explain why DTPA proved to be a better complexing agent than EDTA when not combined with CA.…”

“…DTPA is potentially an octadentate ligand, but typically forms less than 8 bonds with most metal cations, leaving one or two sites available for bonding with other reagents. 34,35 Hence this can explain why DTPA proved to be a better complexing agent than EDTA when not combined with CA. There are several sol-gel syntheses of perovskites reported in the literature in which EDTA and CA are used in combination, and many of them involve basic cations, such as Sr, Ba and La [37][38][39][40][41][42] .…”
