Recycling application of waste long-root Eichhornia crassipes in the heavy metal removal using oxidized biochar derived as adsorbents.
TL;DR: An oxidized biochar was prepared using long-root Eichhornia crassipes through an aerobic/anaerobic hybrid calcination to recycle its waste plants after eutrophic treatments and the adsorption was deduced to be heterozygous courses and mainly controlled by complexation of oxygen-containing groups with these heavy metal ions.

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.

Sorption of dye from aqueous solution by peat
Yuh-Shan Ho,Gordon McKay +1 more
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.

Bio-energy in the black
TL;DR: The precise half-life of biochar is still disputed, and this will have important implications for the value of the technology, particularly in carbon trading as mentioned in this paper, and it is not clear under what conditions, and over what period of time, biochar develops its adsorbing properties.
