Progress in the preparation and application of modified biochar for improved contaminant removal from water and wastewater
TL;DR: Modified biochar (BC) is reviewed in its preparation, functionality, applications and regeneration, and the Langmuir isotherm model provides the best fit for sorption equilibria of heavy metals and anionic contaminants and the pseudo 2(nd) order is the most appropriate model of sorption kinetics for all contaminants.

Kinetics of Adsorption on Carbon from Solution
Walter J. Weber,J. C. Morris +1 more
TL;DR: In this paper, it was shown that the rate of adsorption of persistent organic compounds on granular carbon is quite low and the rate is partially a function of the pore size distribution of the adsorbent, of the molecular size and configuration of the solute, and of the relative electrokinetic properties of adsorbate and adsorbents.

Fluoride in drinking water and its removal.
Meenakshi,R.C. Maheshwari +1 more
TL;DR: It has been concluded that the selection of treatment process should be site specific as per local needs and prevailing conditions as each technology has some limitations and no one process can serve the purpose in diverse conditions.

Preparation and evaluation of a novel Fe-Mn binary oxide adsorbent for effective arsenite removal
TL;DR: The results indicated that phosphate was the greatest competitor with arsenic for adsorptive sites on the adsorbent and was effective for both As(V) and As(III) removal, particularly the As( III).
