Desorption

The removal of binary mixed metal ions [Hg(II), Pb(II), Cu(II) and Cr(III)] from water was investigated. Two different sewage sludge-based adsorbents were produced and used for this purpose: PS, obtained by pyrolysis of sewage sludge, and AS, by ZnCl2 chemical activation of sewage sludge followed by

In this study, a microbial surfactant, rhamnolipid, was investigated for its potential to enhance recovery of Zn(II) from Na-feldspar as soil component. The effects of rhamnolipid concentration, pH, and initial Zn(II) ion concentration on the removal of Zn(II) ions from Na-feldspar by rhamnolipid bi

Activated carbon was developed from coconut coir pith using ZnCl2 and investigated to assess the possible use of this adsorbent for the removal of sulfate from water. The influence of various parameters such as agitation time, sulfate concentration, adsorbent dose, pH and temperature has been studie

The sorption kinetic and equilibrium data obtained at different water activities allowed us to determine the water sorption isotherms and mean diffusion coefficient in the Nafion® membrane. The water sorption isotherm is reminiscent of systems in which there is water clustering at high water activit
