Biosorption equilibrium and kinetics of Cd2+ and Cu2+ ions on wheat straw, Triticum
aestivum, in an aqueous system were investigated. Among the models tested, namely the …

The general principles of cation binding to humic matter and the various aspects of modeling
used in general-purpose speciation programs are discussed. The discussion will focus on …

This work is aimed at quantifying the main environmental factors controlling isotope
fractionation of Cu during its adsorption from aqueous solutions onto common organic …

The effects of humic acid (HA) and heavy metals (Cu 2+ and Ag+) on the sorption of polar
and apolar organic pollutants onto biochars that were produced at temperatures of 200° C …

Integral sugarcane bagasse fibres of about 2 cm length that were pre-treated for removal of
greases and sugars were carboxymethylated on their surface, retaining about 20% of …

Copper (II) ions adsorbed on rice husk (RH), cellulose extracted from rice husk (RH-
cellulose), rice husk heated to 300° C (RHA300) and rice husk heated to 500° C (RHA500) …

Carbon nanotubes (CNTs), a new crystalline form in the carbon family, have been shown to
be an effective adsorbent for Cu2+ ion removal from aqueous solution. After oxidation with …

The capability of wheat straw to adsorb Ni2+ and Zn2+ was investigated using a batch
system. The equilibrium removal of metal ions was obtained between 2.5 and 5h for Ni2+ …

Zn+ 2 and Ni+ 2 in a solution were removed by biosorption in a fixed bed of wheat straw
Triticum aestivum. The removal rate and the mass transfer coefficient for Zn+ 2 and Ni+ 2 …

The sorption of Cu on five vineyard soils was examined via macroscopic and spectroscopic
investigations. The composition of the soils was previously determined using X-ray …
