1) activated coal
In this paper it is proved that regularities of isothermal absorption of activated coal and petrcleum coke for cyanide in water agrees with Langmuir equation.
The absorption system of LAS - Na on active coal, activated coal andpyrobituymen was conducted to study their absorption ability and the relationship betweenabsorption and concentration.
Regularities of absorption of phenol in water on activated coal have been figured out in present paper.
2) activation of lignite
3) activated coal ash
This paper studied the adsorption of activated coal ash on COD in waste leachate.
This paper studied the adsorption of activated coal ash on Cr6+ in waste leachate.
4) activated fly ash
The effects of activated fly ash (AFA) on cement setting time and mortar strength are studied.
This paper studies the feasibility of laboratory wastewater treatment by Fenton oxidation and activated fly ash adsorption.
5) fly-ash activation
This paper makes experiments on the effect of fly-ash activation on early strength of concrete.
6) activated coal gangue
Orthogonal experiment on using activated coal gangue and fly ash to produced composite cement;
The adsorption experiment of chromium(Ⅵ) in simulation wastewater by activated coal gangue is studied.
Pozzuolanic reaction of activated coal gangue mixed with calcium hydroxide and gypsum at various temperatures was investigated by means of differential scanning calorimetry, X-ray diffraction analysis and environmental scanning electron microscope with field emission gun.
