Enhanced separation of base metal sulfides in flotation systems using Chitosan-grafted-Polyacrylamides
TL;DR: In this paper, a chitosan-grafted polyacrylamide (Chi-g-PAM), a synthetic biocompatible polymer was investigated as a selective depressant of iron sulfide minerals [i.e., pyrite (FeS2)] in the flotation process of base metal sulfide mines.

Trimellitated sugarcane bagasse: A versatile adsorbent for removal of cationic dyes from aqueous solution. Part II: Batch and continuous adsorption in a bicomponent system.
Renata Aparecida Fideles,Filipe Simões Teodoro,Amália Luísa Pedrosa Xavier,Oscar Fernando Herrera Adarme,Laurent Frédéric Gil,Leandro Vinícius Alves Gurgel +5 more
TL;DR: The results obtained from the bicomponent batch and continuous adsorption showed that the presence of ST most affected the AO adsorptive system more than the existence of AO affected the ST advertisersorption.

The adsorption of gases on plane surfaces of glass, mica and platinum.
TL;DR: In this article, the absorption index at the wave length of the band maximum was found to be proportional to the total concentration of metal at shorter wave lengths, however, deviations were observed, the absorption increasing more rapidly with concentration than Beers' law would demand.

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.
