Background: Iron is an essential mineral for normal cellular physiology but its ‎overload can lead to cell injury. For many years, deferoxamine injection has been used ‎as an iron chelator for treatment of iron overload. The aim of this study is to compare ‎oral deferoxamine, activated charcoal, and vitamin C, as an absorbent factor of Fe, in ‎changing the serum level of iron in iron overload r...

a carbamazepine intoxication with attempt is a relatively common clinical problem that presenting with coma, respiratory depression, arrhythmia, hemodynamic instability and even death. we report a case of severe carbamazepine poisoning that was successfully treated with one session charcoal hemoperfusion. on admission, the patient was comatose and required ventilator support. hemoperfusion with...

Charcoal records from lake sediments may show changes in fire frequency over thousands of years, but such records are ambiguous with regard to the actual locations of fires. Using a comparison of fire dates from an 1800-year lake sediment record from the west coast of Vancouver Island (British Columbia, Canada) and dates of last fire from 38 sites in the same watershed using tree-ring and soil-...

chromium (cr) is one of the elements presents in crust of the earth. due to its toxicity, chromium is considered as water contaminant that may disturb metabolic activity. in the present study, adsorption of dissolved chromium (vi) onto elaeagnus angustifolia fruit charcoal, jujube fruit charcoal and the standard granular activated carbon (gac) has been investigated and compared. the effect of c...

A brief review of charge-transfer (CT-) thromatography is presented. Hydrophilic gels such as Sephadex exhibit weak electron acceptor and donor prOperties due to the presence of matrix hydroxyls or matrix-bound water. Stronger O-adsorbents for chromatography in aqueous solutions are obtained by introduction of electron acceptor or donor substituents. The adsorption properties of such gels are d...

background: synthetic dyes have several harmful effects on human health as well as aquatic life. in this study, activated carbon (av-ac), based on aloe vera leaf shells, was used as a novel agricultural adsorbent, one that is low-cost and available for the removal of congo red (cr) as a carcinogenic dye from aqueous solutions. methods: in the batch system, the influence of different parameters ...

the selective reduction of oximes with sodium borohydride (nabh4) in the presence of nano cu and charcoal was investigated. cu nanoparticles are widely used as catalysts; efficacious catalyst: copper and copper alloy nanometer feature high efficacy and selectivity, and can be used as catalyst in some reactions. we have shown that nabh4 in the presence of charcoal is an efficient protocol for th...
