Identification of Surface Functional Group on Activated Carbon from Waste Sago

Production of Activated Carbon from Cellulose Wastes

Cellulose wastes of a wood and paper factory were used to produce activated carbon. Several chemical agents under various conditions were used for production of activated carbon and hence their adsorption properties have been evaluated. In addition the effect of process parameters such as raw material, chemical agent concentration, impregnation ratio, carbonization temperature, carbonization ti...

Efficiency of Powdery Activated carbon in Ammonia-Nitrogen Removal from Aqueous Environments (Response Surface Methodology)

Background & Aims of the Study: Nitrogenous compounds could directly create many problems for human's health and the environment. Thus, removal of nitrogenous compounds is necessary. Among the most important problems, decreasing dissolved oxygen, toxicity for aquatics, eutrophication, converting aerobic medium into anaerobic one and corrosion could be noted. The aim of this stu...

Sorption of Cu(II), Zn(II) and Ni(II) from aqueous solution using activated carbon prepared from olive stone waste

The performance of olive stone activated carbon (OSAC) for sorption of Cu2+, Zn2+ and Ni2+ ions was investigated via batch technique. OSAC materials were prepared under different physially activation conditions. Olive stone waste was physically activated with N2 gas and steam gas at 900oC at 3.5h hold time (OSAC-3) was choice as the best one for Cu2+, Zn2+ and Ni2+ removal. Characterization for...

Study on Pore and Surface Development of Activated Carbon Produced from Iranian Coal in a Rotary Kiln Reactor

Water Pollutants Adsorption through an Enhanced Activated Carbon Derived from Agriculture Waste

Background & Aims of the Study: A high nitrate and arsenic concentration in water resources represent a potential risk to the environment and public health. The present work improved a chemo-physically modified activated carbon derived from walnut shells as an adsorbent to improve nitrate and arsenic removal ability from water. Materials & ...
