Adsorption of Imidazolinone Herbicides on Smectite−Humic Acid and Smectite−Ferrihydrite Associations

open access: yesJournal of Agricultural and Food Chemistry, 2001
Adsorption of imazapyr (IMZ), imazethapyr (IMZT), and imazaquin (IMZQ) was studied on two smectite-humic acid and two smectite-ferrihydrite binary systems prepared by treating a Wyoming smectite with a humic acid extracted from soil (4 and 8% w/w of the smectite) and with just-precipitated synthetic ferrihydrite (8 and 16% w/w of the smectite ...

Smectite Interactions with Flavomononucleotide

Clays and Clay Minerals, 1984
AbstractAdsorption isotherms and UV-visible and Mössbauer spectroscopic data point to specific interactions between flavomononucleotide (FMN) and Fe3+-smectite. The maximum amount of FMN adsorption was 0.3 mmole/g of Fe3+-smectite giving a 1:1 molar proportion of Fe3+ and FMN.

Change in Layer Charge of Smectites and Smectite Layers in Illite/Smectite During Diagenetic Alteration

Clays and Clay Minerals, 1996
AbstractThe changes in amount and location of layer charge during diagenetic alteration have been investigated for smectites and smectite layers of illite/smectite interstratified minerals (I/S) by X-ray powder diffraction analysis with various expansion behavior tests: 1) ethylene glycol (EG) solvation (XRD); 2) K-saturation and EG solvation; 3) Li ...

Chemistry of Smectitic and Illitic Phases in Interstratified Soil Smectite

Soil Science Society of America Journal, 1991
Abstract The objective of this investigation was to determine the elemental composition and mineralogy of the smectitic and illitic phases in interstratified smectite‐illite from a typical upper Midwestern agricultural soil.

Sorption of Phenanthrene by Reference Smectites

Environmental Science & Technology, 2001
Fate and behavior of nonionic hydrophobic organic compounds (HOCs) in the environment is mainly controlled by their interactions with various components of soils and sediments. Due to their large surface area and abundance in many soils, smectites may greatly influence the fate and transport of HOCs in the environment.
