Activated carbons from oil-fired fly ashes
Introduction. The aim of this investigation is to prepare activated carbons with good sorbent characteristics from oil-fired fly ash, looking for suitable activation processes to produce surface sites with high reactivity on the carbonaceous matrices [1-4]. In particular, the nitrogen surface sites, formed by gaseous ammonia reaction at 800°C, could greatly increase the adsorption of gaseous sp...
متن کاملOn the Radioactivity of Fly Ashes from Coal Power Plants
The radioactivity of Greek lignites and their ashes was studied. It was found that the radionuclides in them belong to the uranium series. Fly ashes are relatively rich in radioactivity. Concentrations up to 7 , 1 0 _ 5 g / g and 12 pCi/g were measured for 238U and 226Ra, respectively. The associated hazards from radioactivity escaping from stacks of thermopower plants or when fly ashes are use...
متن کاملRadioactivity of Coals and Fly Ashes
Coal, like most materials found in nature, contain trace quantities of the naturally occurring primordial radionuclides. Therefore, the combustion of coals results in the release into the environment of some natural radioactive elements and in a redistribution of these radioactive elements in the surface soil particularly in the vicinity of coal-fired power plants, where it can modify ambient r...
متن کاملArsenic and selenium capture by fly ashes at low temperature.
Arsenic and selenium compounds may be emitted to the environment during coal conversion processes, although some compounds are retained in the fly ashes, in different proportions depending on the characteristics of the ashes and process conditions. The possibility of optimizing the conditions to achieve better trace element retention appears to be an attractive, economical option for reducing t...
متن کاملTrace determination and separation of tin (II) by floatation-spectrophotometric using kalmagyte and CTAB
ABSTRACTA novel floatation-spectrophotometric extraction method was developed for the recovery of tin (II) from aqueous samples prior to determination by UV spectrophotometric detection. The method is based on the formation of a complex between tin (II) and kalmagyte in pH=8. The complex is floated in the interface of n-hexane and aqueous phases. After removing the aqueous phase, the floated pa...
