Kinetic and equilibrium studies of methylene blue removal from aqueous solution by adsorption on treated sawdust

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2010
The aim of this study is to use treated sawdust as an adsorbent for the removal of methylene blue (MB) dye. The adsorption equilibrium and kinetics of methylene blue dye on this adsorbent were then examined at 25 ºC.

Interfacial adsorption characteristics of surfactant‐modified nanoparticles: Equilibrium and dynamic effects of salinity at the oil–water interface

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Surfactant‐modified nanoparticles adsorb at the oil–water interface, enabling interfacial stabilization and microemulsion formation. Abstract This study systematically investigated the interfacial behaviour of silicon dioxide (SiO2) and aluminium oxide (Al2O3) nanoparticles (NPs) functionalized with cationic (CTAB), anionic (SDS), and nonionic (Triton ...

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Phosphorus retention capacity in red ferralitic soil [PDF]

open access: yes, 2014
In this study the main physical-chemical characteristics of red ferralitic soil to use as substrate in subsurface wetlands was determined. The P-removal was evaluated in a short-term isotherm batch experiment and in a column percolation experiment.

Metal‐Free Submicron‐Hollow‐Fiber Conjugated Polymer Sponges for Efficient Pollutant Removal and Thermal Insulation

open access: yesSmall, EarlyView.
Mimicking natural tubular structures, metal‐free conjugated hollow fibers are synthesized via one‐pot Chichibabin condensation. Pyridinic networks spontaneously self‐assemble into submicron hollow fibers and entangle into spongy monoliths—without templates, metals, or post‐processing.

Effect of pyrolysis temperature on ochratoxin A adsorption mechanisms and kinetics by cashew nut shell biochars [PDF]

open access: yes, 2019
Biochars were produced from cashew nut shell at 400, 600 and 800°C. Production temperature significantly affected biochar properties and consequently the adsorption mechanisms of ochratoxin A.
