Adsorption properties of Mg-Al layered double hydroxides thin films grown by laser based techniques

► Laser techniques MAPLE and PLD can successfully be used to produce LDHs thin films. ► Hydration treatments of the PLD and MAPLE deposited films lead to the LDH reconstruction effect. ► The Ni retention from aqueous solution occurs in the films via a dissolution-reconstruction mechanism. ► The films are suitable for applications in remediation of contaminated drinking water or waste waters.
