1. Adsorption of Ametryne and Atrazine on an Oxisol, Montmorillonite, and Charcoal in Relation to pH and Solubility Effects

Author:
V. K. Yamane; R. E. Green
Source:
Soil Science Society of America journal 1972 v.36 no.1 pp. 58-64
ISSN:
0361-5995
Subject:
Oxisols; adsorbents; adsorption; ametryn; atrazine; charcoal; montmorillonite; protonation; soil pH; solubility; sorption isotherms; temperature
Abstract:
... Adsorption of ametryne exceeded that of atrazine on soil and montmorillonite at both low and high pH. Ametryne (pKₐ ≅ 4.0) showed a greater increase in adsorption with decrease in pH than atrazine (pKₐ = 1.68). Addition of charcoal to soil masked the effect of soil pH on ametryne adsorption. Adsorption of ametryne on charcoal decreased at the low pH values conducive to ametryne protonation, demons ...
