    Isotherm, kinetic, thermodynamics and reusability data on the adsorption of antidepressant onto silver nanoparticle-loaded biowaste
    (Elsevier Inc., 2021) Akpomie, Kovo G.; Conradie, Jeanet
    There has been an increase in the use of antidepressant drugs owing to significant economic challenges across the globe. Consequently, the increase in production of such drugs has impacted pharmaceutical pollution of industrial wastew- aters discharged into the environment. Hence, there is a need to develop efficient adsorbents for antidepressant wastewa- ter treatment. The impregnation of silver nanoparticles on biowaste was found to be highly effective in the treatment of oil-polluted water but has not been utilized in the adsorp- tion of drugs. Herein, the dataset associated with the adsorp- tion of antidepressants onto Ananas Comosus Peel (AP) and Silver nanoparticle-loaded Ananas Comosus peel (AgAP) was reported. Batch adsorption methodology was used to study the effect of antidepressant concentration (10–50 mg/L), son- ication time (10–120 min), temperature (300–320 K) and adsorbent dosage (0.10–0.18 g). The concentration of an- tidepressant (Nortriptyline) in solution before and after ad- sorption was determined by the UV-Spectrophotometer at a maximum wavelength of 239 nm. The isotherm dataset was obtained from the Langmuir, Freundlich, Temkin and Dubinin-Raduskevich models, while kinetic data was eval- uated by the pseudo-first order-pseudo-second-order, film diffusion and intraparticle diffusion rate equations. The data on the thermodynamics and adsorbent reusability were also provided. The dataset showed an adsorption capacity of 3.27 mg/g and 4.74 mg/g for AP and AgAP, respectively. The dataset is important to material and environmental scientists and revealed the efficiency of AP and AgAP in the treatment of antidepressant wastewater.
