background: presence of heavy metals in leachate due to the biological accumulation characteristics of these materials endangered the living creatures' health especially human. purpose of this study is to study and investigate the possibility of two metals' absorption i.e, lead and cadmium from leachate by natural zeolite clinopteliolit and increase of the ability to absorb the zeolite by modif...

Micro-sorbent traps referred to as microtraps serve as integrated concentration-injection devices for continuous monitoring in gas phase streams. The application of carbon nanotubes as unique sorbents for the fabrication of microtraps for the nano-scale adsorption/desorption of volatile organic molecules is presented in this paper. The microtrap application requires high adsorption capacity as ...

the discharge of lead containing effluents into the environment and water bodies is harmful for the human, animals, aquatic flora and fauna. herein, a novel surface engineered magnetic nanoparticle for removing pb2+ ions was studied. after surface modification of the magnetite by 3-amino-propyltriethoxysilane (aptes) magnetic nanoparticles with covalently linked porphyrins were synthesized. two...

A novel polymeric sorbent has been synthesized by graft copolymerization of crosslinked polyvinyl alcohol with malic acid, and characterized by FTIR, TGA and swelling studies. A suitable and interesting method has been developed for the extraction and separation of lead ion with the graft copolymer. The lead ion uptake capacity of the polymer has been evaluated vis-a-vis varying pH and metal io...

The aim of this study is to investigate the utilization of silkworm cocoon waste, such as pierced or stained cocoons, as a sorbent material for the removal of motor and vegetable oils from water. The oil-sorption capacity, rate and reusability of the material were evaluated. The results show the high sorption capacity of the silkworm cocoon waste sorbent (42-52 g(oil)/g(sorbent) for motor oil a...
