Rapid cationic dye adsorption on polyphenol-extracted coffee grounds-A response surface methodology approach
(Elsevier Science Bv, Amsterdam, 2014)
The Box-Behnken design under the response surface methodology (RSM) with five interacting parameters (adsorbent dose, initial dye concentration, time of agitation, initial solution pH and time of the adsorbent microwave ...
Arsenate adsorption on waste eggshell modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier Science Sa, Lausanne, 2014)
An efficient adsorbents for arsenate removal was developed by modification of calcined eggshell with goethite (calcined eggshell/goethite; sorbent 1), alpha-MnO2 (calcined eggshell/alpha-MnO2; sorbent 2) and hybride system ...
Ultrasonic assisted arsenate adsorption on solvothermally synthesized calcite modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier, Amsterdam, 2014)
A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 ...
