Hexavalent chromium removal in an electrocoagulation column reactor: Process optimization using CCD, adsorption kinetics and pH modulated sludge formation

Chemical engineering research & design, 2019
In this study, hexavalent chromium [Cr (VI)] removal from aqueous solutions by electrocoagulation, using iron electrodes, was optimized for process variables: applied current, initial pH, initial chromium concentration and application time. A four-factor

Kinetic Analysis of Adsorption Processes

SIAM Journal on Applied Mathematics, 1987
The authors derive an explicit solution of an important special case of a kinetic model of adsorption processes proposed by \textit{J. Gani} [Math. Biosci. 1, 545-554 (1967)]. These processes describe a number of different situations, all involving the reversible adsorption of monovalent particles to sites on cell surfaces. Applications to somatic gene

Kinetic Equations for Transfer-Controlled Adsorption Kinetics

Journal of Colloid and Interface Science, 1995
Abstract Kinetic equations are presented for the adsorption of a surfactant from a liquid bulk phase to a liquid/liquid or air/liquid interface, for a situation where diffusion equilibrium between bulk and subsurface is established, and consequently the transfer of surfactant from the subsurface to the surface is the rate-determining step in the ...

Polydisperse mixture adsorption kinetics

AIChE Journal, 1993
AbstractWe present a theoretical study of the adsorption kinetics of particles with a continuous distribution of sizes. If the particles interact with short‐ranged forces, the diminishing rate of adsorption with increasing surface coverage can be attributed to a geometrical blocking effect of the preadsorbed particles.

Adsorption kinetics of prothrombin

Journal of Colloid and Interface Science, 1983
Abstract The adsorption kinetics at the air/water and phospholipid monolayer/water interfaces was determined by measuring the change of surface radioactivity of tritium-labeled prothrombin with time. The adsorption kinetics on the mercury electrode, at different polarizations, was determined by measuring the change in capacitance with time, assuming ...

Adsorption of three pesticides on polyethylene microplastics in aqueous solutions: Kinetics, isotherms, thermodynamics, and molecular dynamics simulation.

Chemosphere, 2020
Microplastics could act as a carrier for pesticides in the water environment and pose a potential risk. This study mainly investigated the effects of reaction time, microplastics dosages, pH, and NaCl salinity on the adsorption characteristics of three ...

Adsorption Kinetics of Polymeric Molecules

2001
This chapter is devoted to discussing measurements of adsorption from simple solutions, desorption by flushing, and several variations of polymer/polymer exchange. It reviews theory that is relevant to each of the sub processes mentioned. The chapter discusses some frequently applied methods applicable for oxidic surfaces and also reviews experimental ...
