Evaluation of the thermodynamic parameters for the adsorption of some hydrocarbons on chemically treated-bentonites by inverse gas chromatography
Inverse gas chromatography has been used to evaluate the adsorption parameters (?H a, ?H st, ?S a and ?G a) of some probe molecules, each representing a class of organic (n-hexane, cyclohexane, benzene, n-octane, 1-octene ...
Adsorptive features of polyacrylamide-apatite composite for Pb2+, UO22+ and Th4+
(ELSEVIER SCIENCE BV, 2009)
Micro-composite of polyacrylamide (PAA) and apatite (Apt) was prepared by direct polymerization of acrylamide in a suspension of Apt and characterized by means of FT-IR, XRD, SEM and BET analysis. The adsorptive features ...
Removal of copper from aqueous solutions by phosphate rock
A study was carried out to examine the removal of copper from an aqueous solution by phosphate rock (PR). The adsorption method was applied and optimum conditions for adsorption were evaluated by changing various parameters; ...
Removal of Cu(II), Zn(II) and Co(II) ions from aqueous solutions by adsorption onto natural bentonite
In this study, the removal of Cu(II), Zn(II) and Co(II) ions from aqueous solutions using the adsorption process onto natural bentonite has been investigated as a function of initial metal concentration, pH and temperature. ...
