Adsorption of Cu(II), Cd(II) and Ni(II) ions by cross-linked magnetic chitosan-2-aminopyridine glyoxal Schiff's base
TL;DR: Thermodynamic parameters revealed the feasibility, spontaneity and exothermic nature of adsorption, and the sorbents were successfully regenerated using EDTA and HCl solutions.
Journal ArticleDOI
Adsorption of aluminum and lead from wastewater by chitosan-tannic acid modified biopolymers: Isotherms, kinetics, thermodynamics and process mechanism.
TL;DR: The modified biopolymers were efficient biosorbents for removal of Pb(II) and Al(III) metal ions from the medium and increased considerably with the increase of the biosorbent amount and pH of the medium.
Journal ArticleDOI
Equilibrium and kinetics of adsorption of phosphate onto iron-doped activated carbon
TL;DR: Results suggest that the main phase formed in AC/N-FeII and AC/n-FeIII is goethite and akaganeite, respectively; the presence of iron oxides significantly affected the surface area and the pore structure of the activated carbon.
Journal ArticleDOI
Adsorption thermodynamic and kinetic studies of Pb(II) removal from water onto a versatile Al2O3-supported iron oxide
TL;DR: In this paper, the use of activated alumina-supported iron oxide (denoted as FeAA), which is a byproduct of the wastewater treatment plant, has been investigated for wastewater treatment.
Journal ArticleDOI
Effect of surface modification of an engineered activated carbon on the sorption of 2,4-dichlorophenoxy acetic acid and benazolin from water.
TL;DR: The herbicide sorption process was controlled by a film diffusion mechanism and the modified carbon marginally out-performed the conventional activated carbon for sorption of these two herbicides.

Helical microtubules of graphitic carbon
TL;DR: Iijima et al. as mentioned in this paper reported the preparation of a new type of finite carbon structure consisting of needle-like tubes, which were produced using an arc-discharge evaporation method similar to that used for fullerene synthesis.

TL;DR: In this article, a gas can condense to high density inside narrow, single-walled nanotubes (SWNTs) under conditions that do not induce adsorption within a standard mesoporous activated carbon.
Book
Handbook on the toxicology of metals
TL;DR: Handbook of the Toxicology of Metals as discussed by the authors is the standard reference work for physicians, toxicologists and engineers in the field of environmental and occupational health, which is a comprehensive review of the effects on biological systems from metallic elements and compounds.

Stress-induced fragmentation of multiwall carbon nanotubes in a polymer matrix
TL;DR: In this article, the authors report the observation of single nanotube fragmentation, under tensile stresses, using nanotubes-containing thin polymeric films, and they estimate that the multi-wall multi-nanotube-matrix stress transfer efficiency is at least one order of magnitude larger than in conventional fiber-based composites.
