Kinetic models of sorption: a theoretical analysis.
TL;DR: The theoretical results (derived equations) show that the observed rate constants of pseudo-first-order and pseudo-second-order models are combinations of adsorption and desorption rate constants and also initial concentration of solute.

Tea waste as a low cost adsorbent for the removal of Cu and Pb from wastewater
TL;DR: In this article, the adsorption of copper and lead ions onto tea waste from aqueous solutions was studied to enable comparison with alternative commonly available absorbents, and the equilibrium data were satisfactorily fitted to Langmuir and Freundlich isotherms.
Journal ArticleDOI
Adsorption of heavy metal ions from aqueous solutions by activated carbon prepared from apricot stone.
TL;DR: The adsorptions of these metals were found to be dependent on solution pH, and highest adsorption occurred at 1-2 for Cr(VI) and 3-6 for the rest of the metal ions, respectively.

Adsorption studies on Citrus reticulata (fruit peel of orange): removal and recovery of Ni(II) from electroplating wastewater
TL;DR: The ability of fruit peel of orange to remove Zn, Ni, Cu, Pb and Cr from aqueous solution by adsorption was studied and the extent of removal was found to be dependent on sorbent dose, initial concentration, pH and temperature.

Heavy metal cation retention by unconventional sorbents (red muds and fly ashes)
TL;DR: In this paper, the sorbent data have been analyzed and fitted to linearized adsorption isotherms, which are believed to constitute a database for the treatment of one industrial plant's effluent with the solid waste of another, and also to utilize unconventional sorbents such as alumina, silica and ferric oxides.
