Abstract

The binding chemistry of heavy metal cations to a thiolated nanoporous solid-phase sorbent is correlated with the Misono softness parameter, allowing for useful prediction of binding capacity.

Graphical abstract

Two unprecedented types of ligands with C2 symmetry, with comparable essential features, are proposed as supports for metal centres in bimetallic promotion of organic syntheses. Preparation and characterization of bis-chelating bipyridine ligands A and X-ray analysis of a related palladium binuclear complex are described. Synthesis and characterization of a dialdehyde intermediate for type B ligands are also reported.

    On the other hand, the increasing atomic radius, ironic radius, or electronegativity, indicate an increasing sorption capacity [47,45,48,49]. Besides, the larger Misono softness value of the metals (3.58 for Pb2+, 2.84 for Cu2+ and 3.03 for Cd2+) improves the sorption efficiency [45,50]. Even, some researchers declared that the borderline hard Lewis acid Pb2+ is more prone to bind to OH- or PO43– group (i.e. the hard Lewis acid) compared with the soft Lewis acid Cd2+ [47].

    Under the dynamic conditions employed in this study, the experimental data suggest that the modified brick possesses a substantial removal capacity for divalent metal ions and is a potentially promising sorbent material. Some authors have established relationships between metal ionic properties and the sorptive capacity of the studied material which can be used to gain information about the nature of interactions involved at the water–solid interface (e.g., Brady and Tobin, 1995; Can and Jianlong, 2007; Mattigod et al., 2006; Trivedi et al., 2001; Zamil et al., 2009). In our studies, we used six divalent metal ions in an attempt to correlate their ionic properties with adsorption capacity and also to explore the possibility of covalent or ionic bonding.
