In the adsorption process, the surface area, pore and particle size distribution and the
chemical structure of the solid and the type of adsorbent are of vital importance. Activated …

Activated carbon (AC) was prepared from low rank Rawdon coal by chemical activation. The
raw and demineralised coals were employed to produce ACs. The effects of …

Coke plant wastewater contains many toxic pollutants such as phenol, cyanide, and
ammonia, etc., handling and disposal of which has a significant impact on the environment …

An alternative use of the abundant and inexpensive lignite (also known as brown coal) as an
industrial adsorbent has been characterised. The adsorptive properties of two Victorian …

In this work, unburnt coal (UC) in bottom ash from coal-fired power plants was soaked in
KOH solution and activated for 1 h at 780° C. The yield of activated carbons varied from 47.8 …

Two commercial activated carbons, one granular and the other pelletized, were impregnated
with aqueous solutions of phosphoric acid (H 3 PO 4), nitric acid (HNO 3), zinc chloride …

A series of new carbonaceous adsorbents has been obtained by means of direct and
physical activation of Polish brown coal, characterised by high mineral matter content. The …

The preparation of cheap nitrogen-enriched materials with large adsorptive capacities and
selectivity towards volatile organic compounds remains a challenge. Ammoxidation has …

This article deals with adsorptive properties of activated carbons (ACs) and fly ashes from
Turkish coal and biomass resources. ACs because of their high surface area, microporous …

A novel activating agent, potassium silicate, was employed in the preparation of hide waste
activated carbon. Effects of different activation temperatures and impregnation ratios on …
