Résumé

Abstract This study underlines a latest approach of preparing Nitrogen carbon nanoparticles fused on zinc oxide nanoparticles nanocomposite (N-CNPs/ZnONPs nanocomposite) for the uptake of copper ions (Cu2+) from wastewater using a sol gel method and applied the metal loaded adsorbent in the latent fingerprint application. N-CNPs/ZnONPs nanocomposite proved to be a good sorbent for the optimal adsorption of Cu2+ at pH 8 and 0.05 g dosage. Langmuir isotherm best fitted the process with the maximum adsorption capacity of 285.71 mg/g that was superior to most values reported in other studies for the removal of Cu2+. At 25 oC, the adsorption was spontaneous and endothermic. Furthermore, Cu2+-N-CNPs/ZnONPs nanocomposite revealed to be sensitive and selective for latent fingerprint (LFP) identification on a variety of porous surfaces. As a result, it is an excellent identifying chemical for latent fingerprint recognition in forensic science.
