chlorination of natural water containing humic compounds, produce significant amount of disinfectant by - products. the most important of such compounds are thlvis and halo acetic acids, suspected to cause cancer in animals and human. studies showed that under usual processes of water treatment plants, thms can not be removed effectively. since chlorination is the final process of treatment, it...

A strategy for the synthesis of hybrid ordered mesoporous silica-carbon (Si/C) materials with moderate pore volume and surface area has been developed from pre-calcinated MCM carbon precursor Tectonagrandis (TG) dry leaves powder by direct loading method. The pre-activated (PAC) TG was prepared assistance sulphuric acid partial chemical activation controlled studies method indicate that PAC is ...

carbon nanostructures are famous structures which are used in several industries such as separation, treatment, energy storage (i.e. methane and hydrogen storage), etc. a successful modeling of activated carbon preparation is very important in saving time and money. there are some attempts to achieve the appropriate theoretical modeling of activated carbon preparation but most of them were almo...

Abstract In this study, polyacrylonitrile (PAN)-based carbon fiber with high nitrogen content was activated at 800 °C sodium carbonate and heat-treated 950 to prepare (ACF), the results of nitrate ion adsorption on prepared ACF are presented. CHN elemental analysis, XPS measurement, Boehm titration were used determine surface functional groups ACF. It is discussed that total amount decreases, w...

Physico-chemical and surface characterization of activated carbon prepared from groundnut shell, an abundantly available carbonaceous solid waste from oil processing mills in India, by chemical activation were carried out. The effect of various activation conditions viz. time, temperature and ZnCl2 / char ratio on the % yield of product and adsorption efficiency in terms of iodine number was st...

Abstract The effects of different absorbent types on changes in benzo[ a ]pyrene (BaP) and volatiles sesame oil during filtration processes were investigated using gas chromatography–mass spectrometry analysis. BaP content was greatly reduced after powdered activated carbons (activated carbon made from peat: PP, coconut shell: PC, wood: PW) comparison to granular GC, GW). also considerably when...
