Abstract
Waste water contaminated with inorganic mercury is considered a serious environmental problem, mainly due to the hazardous effects this contaminant causes on human health. Thus, the present work aims to evaluate the potentiality of the bimetallic nanoadsorbent ((TiO2@MnO2)-NPs) obtained from the biosynthesis in the mercury ions (Hg2+) removal by adsorption. (TiO2@MnO2)-NPs was synthesized from Aloe vera and Matricaria recutita extracts. The nanoadsorbent was characterized by XRD, ZP, and pHZCP. The results confirmed the production of a nanoadsorbent with an average particle diameter around 25 nm. (TiO2@MnO2)-NPs showed negative surface charge (− 11.32 mV), and pHZCP ≈ 7.65. Regarding Hg2+ adsorption, the removal was 86.15%. Adsorption data were fitted by Khan (R2 0.96, qe = 28.07 mg g−1) and intraparticle diffusion (R2 0.97, qt = 28.84 mg g−1) models. Thermodynamics suggested the adsorption is exothermic process (ΔH = − 73.93 kJ mol−1), with decrease of the randomness (ΔS = 0.24 kJ mol−1 K−1) in the solid–liquid interface, being favorable under temperature below 298.15 K (ΔG = − 1.16 kJ mol−1). (TiO2@MnO2)-NPs resulted in more than 80% Hg2+ removal after six cycles of adsorption. Therefore, nanoparticles containing titanium and manganese can be effectively used for the adsorption of Hg2+ ions, collaborating with the environment.
