Implications of layered double hydroxides assembled biochar composite in adsorptive removal of contaminants: Current status and future perspectives

The use of inorganic layer compounds as adsorbents for organic dyes in water treatment is of increasing interest. In this study, an attempt is made for the synthesis of Mg/Al LDHs by the hydrothermal method. The synthesis temperature was found to significantly affect to the structure of layered double hydroxides (LDHs), as pointed out by FT-IR analysis. In addition, an adsorption capacity of the synthesized LDHs against Congo red in aqueous solutions was investigated and also compared the adsorption results with other dyes such as methylene blue and methyl orange.

The objective of the work studied here was to synthesize Layered Double Hydroxides (LDH) with aluminum extracted from saline slags and test their function once calcined into adsorbents/catalysts for use in the removal of emerging contaminants (pharmaceutical compounds) from aqueous media.Two different techniques for the removal of contaminants were tested, adsorption and photocatalysis. In the present work, a new procedure for the recovery of aluminum present in saline slags generated during the secondary recycling processes of aluminum as adsorbent/photocatalyst of diclofenac and salicylic acid, as examples of emerging contaminants, has been reported. Results obtained have been extensively analyzed throughout the present study.
