The influence of surface acidity of activated carbon (AC) was experimentally studied on
adsorption of ammonia (NH3). Coconut shell-based AC was modified by various acids at …

The effect of surface chemistry (nature and amount of oxygen groups) in the removal of
ammonia was studied using a modified resin-based activated carbon. NH3 breakthrough …

Ammonia adsorption was studied under dynamic conditions, at room temperature, on
activated carbons of different origins (coal-based, wood-based and coconut-shell-based …

Accepted: Jul 29, 2013; Published: Aug 07, 2013 Abstract: The study was conducted to
identify the potential used of organic acid modified activated carbon (AC-RCOONa) to …

Elucidation of mechanistic insight into the interaction of carbon materials' physicochemical
surface properties and ammonium (NH 4+) adsorption in aqueous media was made by …

In this work, activated carbons (ACs) were modified by ozone treatment to enhance the
efficiency of removal of ammonia gas over the ACs. Surface properties of the ACs were …

A coconut activated carbon was modified using chemical methods. Different concentration of
nitric acid oxidation of the conventional sample produced samples with weakly acidic …

Adsorptive removal of nitrate ions in aqueous solution using activated carbons (ACs) was
examined. After ash was removed from Filtrasorb 400 AC, oxidation and outgassing and …

Commercial carbons were modified by incipient wetness impregnation with aqueous
solutions of metal salts (Fe, Co, Cr), followed by calcinations at low temperature (300° C) …

The rise in atmospheric pollution caused by gases such as ammonia has led many
researchers to conduct studies aimed at decreasing or treating the emissions of such …
