Daset: Biotemplate-assisted morphology and porosity of nanosilica: eco-friendly synthesis and application as an adsorbent for pharmaceutical contaminants in water

The research hypothesis states that the material exhibits high affinity and retention for both pharmaceuticals under ambient conditions, with rapid kinetics, adsorption dependent on dose and pH, endothermic behavior, and operational stability over multiple reuse cycles.

The dataset includes: (i) dose study (1–80 mg), where increasing mass reduces Ce and increases removal, reaching >98% at high doses; (ii) pH (2–12 and natural), with maximum Qe around pH 6–natural; (iii) stirring speed (0–300 rpm), showing higher removal until stabilization at ~200 rpm; (iv) kinetics (1–120 min) with Ct and Qe series suitable for PFO, PSO, Elovich, intraparticle diffusion, and Bangham models; (v) isotherms at 15, 25, 40, and 55 °C for Langmuir, Freundlich, and Redlich–Peterson fitting; (vi) thermodynamics, with ΔG<0 at all temperatures, ΔH>0, and positive ΔS, indicating endothermic adsorption; (vii) competitive adsorption HCQ+OSEL, reporting individual and total Qe (mmol/g); (viii) reuse over 10 cycles, maintaining high removal with slight gradual decrease.
