TL;DR: In this paper, an acid dye, acid yellow 36, was used as the adsorbate for the removal of acid dyes from aqueous solution and the results showed that a pH value of 3 is favorable for the adsorption of acid dye.

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: From a comprehensive literature review, it was found that some LCAs, in addition to having wide availability, have fast kinetics and appreciable adsorption capacities too.
3,163 citations
TL;DR: In this article, a review of the recent developments in the synthesis of adsorbents containing polysaccharides, in particular modified biopolymers derived from chitin, chitosan, starch and cyclodextrin, is presented.

TL;DR: In this paper, the use of agricultural solid wastes to remove two classes of dye, cationic and anionic dyes, was discussed and a simple comparison among cationi-and anionic dye adsorption by the same adsorbent was made, thus possibly opening the door for a better understanding of the dye-classified adaption process.

TL;DR: In this article, a review of the production of activated carbons from agricultural residues is presented, and the effects of various process parameters on the pyrolysis stage are reviewed.
Abstract: A review of the production of activated carbons from agricultural residues is presented. The effects of various process parameters on the pyrolysis stage are reviewed. Influences of activating conditions, physical and chemical, on the active carbon properties are discussed. Under certain process conditions several active carbons with BET surface areas, ranging between 250 and 2410 m 2 /g and pore volumes of 0.022 and 91.4 cm 3 /g, have been produced. A comparison in characteristics and uses of activated carbons from agricultural residues with those issued from tires, and commercial carbons, have been made. A review is carried out of the reaction kinetic modelling, applied to pyrolysis of agricultural wastes and activation of their pyrolytic char.
