Tailoring boron nitride nanomaterials for sweeping the soil contamination (Ba, As, Se, Co, Cu, Mo): in situ nanosensors modelling towards green chemistry

Nanomaterials adsorb a great variety of contaminants and catalyse reactions by lowering the energy required to break them down, due to their unique surface properties. The target of this research is removing metal, metalloid and non-metal elements of Ba, As, Se, Co, Cu, Mo from soil due to gallium nitride nanocage (B5N10Nc). The sharpest curves for electric potential were nominated for metal, metalloid and non-metal atoms trapped by the B5N10Nc that prove the electron attaining of these elements aided by boron and nitrogen atoms of B5N10Nc: Mo→B5N10Nc>Cu→B5N10Nc>Co→B5N10Nc>As→B5N10Nc≈Se→B5N10Nc>Ba→B5N10Nc. Based on the results in this research, the selectivity of toxic metal, metalloid, and non-metal elements adsorption by B5N10Nc have been indicated as follows: Cu ≈ Co>Mo>>>As ≈ Se>Ba. Moreover, the thermodynamic properties have clarified that the dependence on the size of the atoms of during interaction between the adsorbates of the metal, metalloid and non-metal elements as the electron acceptors and the adsorbent of B5N10Nc as electron donor in the complexes of Ba→B5N10Nc, As→B5N10Nc, Se→B5N10Nc, Co→B5N10Nc, Cu→B5N10Nc, and Mo→B5N10Nc. The present research tries to concentrate on the role of nanoparticles in remediation of contaminated soil based on adsorption system.
