2,4-Dichlorophenoxyacetic acid (2,4-D) sorption and degradation dynamics in three agricultural soils.

The fate and transport of 2,4-dichlorophenoxyacetic acid (2,4-D) in the subsurface is affected by a complex, time-dependent interplay between sorption and mineralization processes. 2,4-D is biodegradable in soils, while adsorption/desorption is influenced by both soil organic matter content and soil pH. In order to assess the dynamic interactions between sorption and mineralization, 2,4-D miner...

Sorption-desorption of indaziflam in selected agricultural soils.

Indaziflam, a new alkylazine herbicide that inhibits cellulose biosynthesis, is under current development for soil applications in perennial crops and nonagricultural areas. Sorption and desorption of indaziflam in six soils from Brazil and three soils from the United States, with different physical chemical properties, were investigated using the batch equilibration method. Sorption kinetics d...

nickel sorption in selected calcareous soils of iran

metals sorption on solid phase from solution is one of the most important chemical processes controlling their bioavailability in soils. nickel (ni) sorption characteristics in 20 calcareous soils of iran were investigated in a range from 5.87 to 751.23 mgl-1 ni concentration in solution using sorption isotherms. ni sorption isotherm exhibited strong nonlinear behavior for all soils. the result...

kinetics of zinc sorption by some calcareous soils of iran

the kinetics of zn sorption by ten calcareous soils of iran were measured and fitted to several equations (zero-, first-, second-, third-order, parabolic diffusion, simple elovich, and exponential equations). two initial concentrations of zinc i.e. 20 and 80 mg zn l-1 were used and observations were carried out for 100 hours. the time required to reach the near equilibrium state was about 24 ho...
