Competitive adsorption of dyes and heavy metals on zeolitic structures
Journal of Environmental Management, 2013The adsorption of Acid blue 25, basic blue 9, basic violet 3, Pb(2+), Ni(2+), Zn(2+) and Cd(2+) ions has been studied in single and dye-metal binary solutions using two mineral materials: Clinoptilolite (CL) and ER (Erionite). These zeolites were characterized by FT-IR spectroscopy; potentiometric titration and nitrogen adsorption isotherms at 77 K to ...

New Prospects for Modified Algae in Heavy Metal Adsorption
Trends in Biotechnology, 2019Heavy metal pollution is one of the most pervasive environmental problems globally. Novel finely tuned algae have been proposed as a means to improve the efficacy and selectivity of heavy metal biosorption. This article reviews current research on selective algal heavy metal adsorption and critically discusses the performance of novel biosorbents.

Adsorption of heavy metals on soil
2020Adsorption-desorption data are the main processesgoverning the mobility of compounds in soil.In this study, the adso:rptioninvestigated on two different soils (from Bursa andIstanbul) for three heavy metals (Cu, Ni, Zn)! andadsorption capacity (K) and adso:rption intensity (l/n)values were found.

Dilatometric Study of the Adsorption of Heavy-Metal Cations on Goethite
Langmuir, 2004The specific volumes of adsorption of Cd, Co, Cu, Ni, Pb, and Zn on goethite determined by means of the dilatometric method are 21, 32, 32, 31, 31, and 42 cm3/mol, respectively, and are independent of pH. The effect of NaCl (up to 0.5 mol dm(-3)) on the specific volume of adsorption is rather insignificant.

Removal of heavy metals by using adsorption on alumina or chitosan
Analytical and Bioanalytical Chemistry, 2003The removal of heavy metals from wastewater by using activated alumina or chitosan as adsorbers was evaluated. Cd(II) and Cr(III) were employed as models of the behaviour of divalent and trivalent metal ions. The adsorption of Cd(II) and Cr(III) onto the adsorbers evaluated was studied as a function of pH, time, amount of adsorber, concentration of ...

Adsorption of heavy metal ions on soils and soils constituents
Journal of Colloid and Interface Science, 2004The article focuses on adsorption of heavy metal ions on soils and soils constituents such as clay minerals, metal (hydr)oxides, and soil organic matter. Empirical and mechanistic model approaches for heavy metal adsorption and parameter determination in such models have been reviewed.
