Background: Removal of heavy metal ions from contaminated systems by agricultural and fruit and vegetable processing waste materials is an innovative and auspicious technology .The current study was designed for utilization of bio-adsorption white hard eggshell, as less expensive and much frequently available food waste materials, due to prospective metal bio-sorption capacity to toxic heavy me...
The present study was carried out to investigate the adsorption and leaching behavior of Cu2+, Zn2+ and Pb2+ by sediments collected from the western banks of three different sectors along River Nile at Aswan governorate, Egypt. The feasibility of sediments for the removal of Cu2+, Zn2+ and Pb2+ from aqueous solutions was tested under the effect of three conditions (pH, initial metal concentrati...
the main objective of the present study is to investigate the feasibility of using carboxymethyl chitosan magnetic nanoparticles (ccmn) for the adsorption of cd2+. the study also reports important parameters, which affect the adsorption process, i.e., ph, adsorbent dose, contact time and concentration of cd2+, using box-behnken designs. firstly, functional carboxymethyl chitosan magnetic nanopa...
Accurate information on heat transfer and temperature distribution in metal foams is necessary for design and modeling of thermal-hydraulic systems incorporating metal foams. The analysis of this process requires determination of the effective thermal conductivity as well as the thermal contact resistance (TCR) associated with the interface between the metal foams and adjacent surfaces/layers. ...
