PDF Arsenic Desorption from Ferric and Manganese Binary ...

The desorption behavior of arsenic in the presence of four competitive anions i.e., phosphate, sili e, sulfate, and bicarbonate at different concentrations was investigated with pH ranging ...

ADSORPTION OF MANGANESE FROM ACID MINE DRAINAGE EFFLUENTS ...

column runs, using a laboratory solution containing 100 mg L -1 of manganese, were also carried out for Adsorption of Manganese from Acid Mine Drainage Effluents Using Bone Char: Continuous Fixed Bed Column and Batch Desorption Stu dies 579

Individual and competitive adsorption of arsenic and ...

Individual and competitive adsorption of phosphate and arsenic onto manganese oxides in seawater Master’s Research Proposal Maryon Paulsen Strugstad Supervisors: Bjorn Sundby, Alfonso Mucci 1. Introduction The amount of phosphate and arsenic in the marine environment is an important indi or for water quality.

A Quantitative Model for the Coupled Kinetics of Arsenic ...

The ability to predict coupled kinetic reactions of arsenic As that occur at the manganese oxide–aqueous solution interface is crucial for management and remediation of As-contaminated sites worldwide. A quantitative understanding of the coupling between As oxidation and adsorption/desorption kinetics will enable us to more accurately predict the kinetic behavior of As. In this study, we ...

Competitive sorption and desorption of heavy metals by ...

In this study the competitive sorption and desorption of Cd, Cr, Cu, Ni, Pb and Zn by humified organic matter, Fe and Mn oxides, kaolinite, vermiculite and mica were investigated. Due to the homogeneity of the sorbents, between-metal competition for binding sites led to their preferences for one or another metal being much more manifest than in ...

Breakthrough Curve Analysis for Column Dynamics Sorption of ...

The sorption performance of the ions through the column was analyzed by Thomas, Yoon-Nelson, and Adams-Bohart models starting at concentration ratio, 𝐶 𝑡 / 𝐶 0 > 0. 1 that is 10% breakthrough until 𝐶 𝑡 / 𝐶 0 > 0. 9 0, that is, 90% breakthrough for manganese by considering the safe water quality standards and operating limit ...
