Adsorption behavior and mechanism of Cd (II) by modified coal-based humin

Adsorption of Ni(II) and Cd(II) from Aqueous Solutions Using Modified Rice Husk

Background and purpose: Recently, release of pollutants such as heavy metal ions to the environment becomes one of the most important problems for soil and water. The present study was conducted to introduce modified rice husk (RH) as a new low-cost adsorbent. Materials and Methods: In this study, tartaric acid modified RH (TARH), was used as an adsorbent for removal of Ni(II) and Cd(II) from w...

Adsorption of Cd(II) by Dried Activated Sludge

Adsorption of Ni(II) and Cd(II) Ions from Aqueous Solutions by Modified Surface of Typha latifolia L. Root, as an Economical Adsorbent

The modified surface of Typha latifolia L. root (MSTL), as an alternative economical adsorbent, wasused for the removal of Ni (II) and Cd(II) ions from aqueous solutions. The effect of initial pH, initialconcentration of metal ion, and contact time was investigated in a batch system at room temperature.The kinetics data could be fitted well by pseudo-second-order model with correlation coeffici...

Experimental modeling of the adsorption kinetics of Cd (II) and Pb (II) ions by Calix [4] arene surface

The removal of Cd2+ and Pb2+ ions from wastewater using p-tert-butyl-calix[4] arene was investigated in terms of initial pH, initial concentration, adsorbent dosage, contact time and temperature. The maximum adsorption occurred at the pH value of 6. The adsorbent studied exhibits high efficiency for Cd (II)and Pb (II) adsorption and the equilibrium states could be achieved in 10 min.
