A magnetic nano-sorbent incorporating antimicrobial papain for the rapid and efficient removal of levofloxacin and Pb(ii) from aqueous systems

Abstract

In the contemporary century, bio-based magnetic nanomaterials have received tremendous interest as promising candidates in adsorption procedures owing to their magnetic nature, modifiability, approachability, bioactivity, and pH-responsive dynamics.

Sustainable high-efficiency removal of cationic and anionic dyes using new super adsorbent biochar: performance, isotherm, kinetic and thermodynamic evaluation

“…This suggests the potential role of liquid-film diffusion mechanism in the rate-limiting step of MG adsorption in the initial 60 minutes. 81 The fitting of kinetic data for Ice-Bio 700/CR yielded R 2 = 0.993 which is greater than Ice-Bio 700/MG indicating the predominance of the LFD model in CR removal compared to MG.…”

Bangham diffusion model. The Bangham equation model was developed based on the hypothesis that pore diffusion was the sole rate-limiting stage during the adsorption process.…”

Comprehensive analysis of cationic dye removal from synthetic and industrial wastewater using a semi-natural curcumin grafted biochar/poly acrylic acid composite hydrogel

“…The Q e vs. C i graph shows that Q e values ascend steeply at lower concentrations, but with the relative saturation of the adsorbent at high concentrations and E-repulsion between adsorbate molecules and adsorbed species on the active sites, the graph tends to a quasi-linear state and the range of alters decreases. 80…”
