TL;DR: In this paper, the adsorption of Congo Red by coir pith carbon was carried out by varying the parameters such as agitation time, dye concentration, adsorbent dose, pH and temperature.
1,357 citations
TL;DR: Kinetic study showed that the adsorption of dye on coir pith carbon was a gradual process and pH effect and desorption studies suggest that chemisorption might be the major mode of the Adsorption process.
868 citations
TL;DR: The percent adsorption increased with increase in pH from 2 to 6 and remained constant up to 10 and the resulting carbon is expected to be an economical product for the removal of toxic heavy metals from industrial wastewaters.
750 citations
TL;DR: In this paper, the adsorption of dyes such as congo red, procion orange and rhodamine-B by waste orange peel was examined at different concentrations of dye, adsorbent dosage, agitation time and pH.
585 citations
TL;DR: The effectiveness of orange peel in adsorbing Acid violet 17 from aqueous solutions has been studied as a function of agitation time, adsorbent dosage, initial dye concentration and pH.

TL;DR: In this paper, a literature review of the use of sorbents and biosorbents to treat polluted aqueous effluents containing dyes:organics or metal ions has been conducted.
13,746 citations
TL;DR: It is evident from the literature survey articles that ion-exchange, adsorption and membrane filtration are the most frequently studied for the treatment of heavy metal wastewater.
6,844 citations
TL;DR: It is evident from a literature survey of about 210 recent papers that low-cost sorbents have demonstrated outstanding removal capabilities for certain dyes, and chitosan might be a promising adsorbent for environmental and purification purposes.
3,906 citations
TL;DR: In this paper, the sorption of two dyes, namely Basic Blue 69 and Acid Blue 25 onto peat has been studied in terms of pseudo-second order and first order mechanisms for chemical sorption as well as an intraparticle diffusion mechanism process.
3,502 citations
TL;DR: An overview of second-order kinetic expressions is described in this paper based on the solid adsorption capacity, which shows that a pseudo-second-order rate expression has been widely applied to the Adsorption of pollutants from aqueous solutions onto adsorbents.
