Adsorption of phenol and its derivatives from water using synthetic resins and low-cost natural adsorbents: a review
Su-Hsia Lin,Ruey-Shin Juang +1 more
TL;DR: The technical feasibility of the use of activated carbon, synthetic resins, and various low-cost natural adsorbents for the removal of phenol and its derivatives from contaminated water has been reviewed and it should be noted that the adsorption capacities of the adsorbent vary significantly depending on the characteristics of the individual adsorbENT, the extent of chemical modifications, and the concentrations of solutes.

Adsorption properties and breakthrough model of 1,1-dichloro-1-fluoroethane on activated carbons
TL;DR: The experimental results show that within the experimental conditions, the adsorption capacities of the two adsorbents for HCFC-141b in dry air streams can be well-fitted by the Langmuir, Freundlich, and Dubinin-Radushkevich (D-R) Adsorption equations.

Investigation of the combined effects of external mass transfer and biodegradation rates on phenol removal using immobilized P. putida in a packed-bed column reactor
Zümriye Aksu,Gültaç Bülbül +1 more
TL;DR: A quantitative analysis of external mass transfer combined with a biodegradation reaction and correlation of the experiment with theory was performed for phenol removal using calcium-alginate gel-immobilized P. putida in a packed-bed column reactor and it was decided that the mass transfer correlation j D = 1.625 Re −0.507 accurately predicted experimental data.
