background and aims: the removing of (potential) toxic heavy metal ions from sewage, especially in industrial and mining waste effluents, has been widely studied in recent years. the aim of present study was to investigate the various methods for lead removal of lead ions from industrial wastewater. methods: this study was a review research. data were collected through different databases in va...

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...

Explantation of chronically implanted pacemaker or defibrillator leads can be technically demanding. We present the results of the first 44 leads extracted with excimer laser sheaths in 25 patients with a median lead implantation time of 7 years (range: 2 to 20 years). Indications for extraction were lead fracture in 17 patients, pocket infection in 4, septicemia in 2, and lead endocarditis in ...

background: today, issues such as water shortage, difficulties and costs related to supplying safe water, and anomalous concentrations of heavy metals in groundwater and surface water resources, doubled the necessity of access to technical methods on removing these pollutants from water resources. methods: in this lab study, cationic resin purolite s-930 (with co-polymer styrene di-vinyl benzen...
