Abstract:Sorption data analysis was carried out using the Freundlich, Langmuir, and Modified Freundlich isotherms for the uptake of sodium and potassium in an initial concentration range of 10-100 mg/L on backfill materials, viz., bentonite, vermiculite, and soil samples. The soil samples were collected from a shallow land disposal facility at Kalpakkam. The Freundlich isotherm equation is validated as a preferred general mathematical tool for representing the sorption of K + by all the selected backfill materials. The… Show more
ABSTRACT:The adsorption behavior of a hemoglobin (Hb) solution onto bentonite powder was studied from its alkaline solution (pH 12.6) and at room temperature. Different types of adsorption isotherms are discussed and various adsorption parameters, such as the adsorption coefficient, rate constants for adsorption and desorption, diffusion constant, penetration rate constant, were evaluated. The effects of pH and temperature of the adsorption medium on the extent of adsorption and the influence of solvents were studied, and the effect of salt concentrations on the rate of adsorption were also observed.

“…Thus, the sorption of strontium from a hydrothermal solution by Montmorillonite increases by 30% if the Sr 2+ ions sorb together with Li + ions. 195 An analogous positive cosorption of these elements by soils was described by Chitra et al 196 The adsorption of carbon monoxide on SiO 2 from a gaseous phase is negligible under ordinary conditions if the sorbent is not doped with a silver salt. The adsorption is enhanced if the sorbent contains silver.…”
