Journal ArticleDOI
Arsenic removal from water/wastewater using adsorbents—A critical review
Dinesh Mohan,Charles U. Pittman +1 more
TL;DR: Strong acids and bases seem to be the best desorbing agents to produce arsenic concentrates, and some commercial adsorbents which include resins, gels, silica, treated silica tested for arsenic removal come out to be superior.
Journal ArticleDOI
Organic and inorganic contaminants removal from water with biochar, a renewable, low cost and sustainable adsorbent--a critical review.
TL;DR: A review of recent applications of biochars, produced from biomass pyrolysis (slow and fast), in water and wastewater treatment, and a few recommendations for further research have been made in the area of biochar development for application to water filtration.
Journal ArticleDOI
Activated carbons and low cost adsorbents for remediation of tri- and hexavalent chromium from water.
Dinesh Mohan,Charles U. Pittman +1 more
TL;DR: The sorption capacities of commercial developed carbons and other low cost sorbents for chromium remediation are provided, and particular attention is paid to comparing the sorption efficiency and capacities of commercially available activated carbons to otherLow cost alternatives.
Journal ArticleDOI
Pharmaceuticals of Emerging Concern in Aquatic Systems: Chemistry, Occurrence, Effects, and Removal Methods.
TL;DR: Adsorption technologies are a low-cost alternative, easily used in developing countries where there is a dearth of advanced technologies, skilled personnel, and available capital, and adsorption appears to be the most broadly feasible pharmaceutical removal method.
Journal ArticleDOI
Sorption of arsenic, cadmium, and lead by chars produced from fast pyrolysis of wood and bark during bio-oil production
Dinesh Mohan,Charles U. Pittman,Mark Bricka,Fran Smith,Ben Yancey,Javeed Mohammad,Philip H. Steele,María Alexandre-Franco,Vicente Gómez-Serrano,Henry Gong +9 more
TL;DR: Oak bark out-performed the other chars and nearly mimicked Calgon F-400 adsorption for lead and cadmium, and the oak bark char's ability to remove Pb(II) and Cd( II) is remarkable when considered in terms of the amount of metal adsorbed per unit surface area.
