Title : Novel development of zinc oxide coated zarbon nanoparticles from pineapples leaves using sol gel method for optimal adsorption of Cu 2+ and reuse in latent fingerprint.

Abstract:

This study underlined a latest approach of preparing Nitrogen carbon nanoparticles fused on zinc oxide nanoparticle nanocomposite (N-CNPs/ZnONPs nanocomposite) for the uptake of copper ions (Cu²⁺) from wastewater using a sol gel method and apply the metal loaded adsorbent in 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 value 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.
