Novel Silica-Based Hybrid Adsorbents: Lead(II) Adsorption Isotherms
The Scientific World Journal, 2013 Water pollution caused by the lead(II) from the spent liquor has caught much attention. The research from the theoretical model to application fundaments is of vital importance. In this study, lead(II) adsorption isotherms are investigated using a series

Tailoring Biomass‐Derived Organosolv Lignin Derivatives for High‐Capacity Adsorption of Rhodamine B [PDF]
ChemSusChemOrganosolv lignin derivatives modified with phenolic compounds were synthesized via a one‐step lignin‐first approach and evaluated as renewable adsorbents for removing Rhodamine B dye from water. Among them, resorcinol‐modified lignin showed the highest adsorption capacity (101 mg g−1), driven by high surface area, pore volume, and accessible hydroxyl ...

Kinetic study of defluoridation of drinking water by electrocoagulation/electroflotation in a stirred tank reactor and in an external-loop airlift reactor [PDF]
, 2010 A kinetic study of defluoridation of drinking water was carried out using the electrocoagulation/electroflotation process in two batch reactors of identical volume (20 L): a stirred tank reactor (STR) and an external-loop airlift reactor (ELALR).

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

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The continuous increasing discharge of synthetic dyes into aquatic systems seems to be an important environmental and health risk due to their high toxicity and resistance to biodegradation. Among these dyes, methylene blue (MB) and Congo red (CR) are widely used in textile and industrial applications, necessitating sustainable and efficient ...

Dissolved humic substances supplied as potential enhancers of Cu, Cd, and Pb adsorption by two different mangrove sediments [PDF]
, 2018 Purpose The external supply of humic substances has been recently suggested for the remediation of metal-polluted sediments; however, little is known about how to supply them and their effects on metal mobility.

Adsorption Characteristics and Mechanisms of Dibutyl Phthalate on Nanomaterials
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Dibutyl phthalate (DBP) is a widely used plasticizer whose environmental release poses significant risks to ecosystems and human health. This study systematically investigated DBP adsorption on three common nanomaterials—titanium dioxide nanoparticles (n‐TiO2), multiwalled carbon nanotubes (MWCNTs), and carboxylated MWCNTs (MWCNTs‐COOH)—using ...
