Methylene Blue Adsorption from Aqueous Solution by Magnetic Cellulose/Graphene Oxide Composite: Equilibrium, Kinetics, and Thermodynamics
TL;DR: In this article, a magnetic cellulose/graphene oxide composite (MCGO) was prepared as a novel adsorbent to dispose of dye wastewater, and the morphology and chemical structure of the MCGO composite were characterized by the Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD), and scanning electronic microscope (SEM).

Removal of mercury by adsorption: a review
TL;DR: It is evident from the literature survey that some adsorbents have shown excellent potential for the removal of mercury, however, there is still a need to develop novel, efficient adsorbent with low cost, high stability, and easy production and manufacture for practical utility.

Efficient Removal of Heavy Metals from Polluted Water with High Selectivity for Mercury(II) by 2-Imino-4-thiobiuret–Partially Reduced Graphene Oxide (IT-PRGO)
Fathi S. Awad,Fathi S. Awad,Khaled M. AbouZeid,Weam M. Abou El-Maaty,A. M. El-Wakil,M. Samy El-Shall +5 more
TL;DR: The sorption kinetics can be fitted well to a pseudo-second-order kinetic model which suggests a chemisorption mechanism via the amidinothiourea groups grafted on the reduced graphene oxide nanosheets as a top performing remediation adsorbent for the extraction of heavy metals from waste and polluted water.

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.

Heavy metals (Cd, Pb, Zn, Ni, Cu and Cr(III)) removal from water in Malaysia: Post treatment by high quality limestone
TL;DR: Investigations on the removal behaviour of these metals indicated that rough solid media with the presence of carbonate were beneficial for the removal process, and Adsorption and precipitation as metals oxide and probably as metals Carbonate were among the two mechanisms that contributed to the removal of metals from solution.

Aminated polyacrylonitrile fibers for lead and copper removal
Shubo Deng,Renbi Bai,Chen Jp +2 more
TL;DR: In this article, Aminated polyacrylonitrile fibers (APANFs) were used as an adsorbent to remove lead and copper ions from aqueous solutions and it was found that the zero ζ potential point of the APANFs was at about pH = 8.1, in contrast with that of the PANFs at pH = 3.6.
