Abstract:

Removal of lead ions from aqueous solutions by Tamrix gallica leaves was studied. The factors that affected this removal were investigated. These factors are metal ion concentration, tamrix leave concentration, pH, presence of competing ions, agitation, crushing, drying, presence of complexing agent, and leaf extract. Application of the Freundlich adsorption isotherm on the present results has been examined and the parameters of this isotherm have been calculated. The order of reaction between lead ions and Tamrix gallica leaves has been determined and a mechanism for this interaction has been suggested. Key words: lead removal, Tamrix leaves, adsorption, pH.

Le retrait des ions de plomb de solutions aqueuses en utilisant des feuilles de Tamrix gallica a été étudié. Nous avons examinée les facteurs affectant ce déplombage, soit : la concentration en ions métalliques, la concentration en feuilles de Tamrix, le pH, la présence d'ions concurrents, l'agitation, le broyage, le séchage, la présence d'un agent complexant et l'extrait de feuilles. Nous avons ensuite étudié l'application de la formule d'adsorption de Freundlich sur ces résultats et calculé les paramètres de cet isotherme. L'ordre de la réaction entre les ions de plomb et les feuilles de Tamrix gallica a été déterminé et nous suggérons un mécanisme pour expliquer cette interaction. Mots clés : déplombage, feuilles de Tamrix, adsorption, pH.[Traduit par la rédaction]

Keywords: lead removal, Tamrix leaves, adsorption, pH, déplombage, feuilles de Tamrix, adsorption, pH
