Removal of phenol from wastewater by different separation techniques
Wojciech Kujawski,Andrzej Warszawski,Włodzimierz Ratajczak,Tadeusz Porebski,W. Capała,Izabela Ostrowska +5 more
TL;DR: In this paper, application of membrane techniques (pervaporation and membrane-based solvent extraction) and adsorption to the removal of phenol from solutions modelling wastewater from phenol production by cumene oxidation process was investigated.

The application of macroporous resins in the separation of licorice flavonoids and glycyrrhizic acid.
TL;DR: The performance and adsorption characteristics of four widely used macroporous resins for the separation of deglycyrrhizinated, flavonoids enriched licorice has been critically evaluated and XDA-1 offers much higher adsorptive capacity for GA and LF than other resins, and its adsor adaptation data fit the best to the Freundlich isotherm.

Optimization of luteolin separation from pigeonpea [Cajanus cajan (L.) Millsp.] leaves by macroporous resins
TL;DR: AL-2 resin offers the best adsorption and desorption capacity for LU than other resins based on the research results and may provide scientific references for the large-scale LU production from pigeonpea or other plants extracts.

Adsorption of amoxicillin on chitosan beads: Kinetics, equilibrium and validation of finite bath models
Wellington Sabino Adriano,Vinicius de Veredas,Cesar Costapinto Santana,Luciana Rocha Barros Gonçalves +3 more
TL;DR: The fit to experimental equilibrium data indicates that the isotherm for this system can be considered of Langmuir type and optimizing mass transfer parameters, that describe the phenomena of internal diffusion and external convection on chitosan beads, as well as determining the kinetic rate constant.
Journal ArticleDOI
Amino acid adsorption on mesoporous materials: influence of types of amino acids, modification of mesoporous materials, and solution conditions.
TL;DR: All the adsorption of amino acids on mesoporous silica materials can be decided by the combined influence of two fundamental interactions: electrostatic attraction and hydrophobic effect.

Design of cyclic fixed‐bed adsorption processes. Part I: Phenol adsorption on polymeric adsorbents
Carlos Costa,Alírio E. Rodrigues +1 more
TL;DR: In this article, a model for the adsorption of phenol in a fixed bed of a polymeric adsorbent is developed, which is used for the prediction of breakthrough curves and is part of a package for the design of cyclic processes.
