A composite adsorbent La/Fe/FA for reactive turquoise blue KN-G (RTB KN-G) and reactive brilliant blue KN-R (RBB KN-R) removal from aqueous solution was prepared by loading lanthanum (III) and iron (III) onto waste coal fly ash (FA). The adsorption behavior of RTB KN-G and RBB KN-R on La/Fe/FA was investigated systematically. The results show that the initial dye concentration, contact time, pH value and temperature are all the important factors influencing the adsorption. The adsorption of La/Fe/FA for two reactive dyes at different temperatures were very fast and can establish sorption equilibrium at 30min, and agreed well with pseudo-second-order kinetics. The equilibrium adsorption data could be described by the Langmuir isotherm equation well, and obtained maximum adsorption capacities at 25°C were 56.28 mg/g for RTB KN-G and 116.82mg/g for RBB KN-R, respectively. The rise of temperature was not conducive to adsorption. The results show that the La/Fe/FA adsorbent displays high effective adsorption for reactive dyes and will have potential as a promising application in the field of water pollution control and recycling utilization of resources.

Coal Power Stations

The present work examines the possible use of fly ash, a byproduct of coal power stations, as a means of removing phenol from water, or equivalently, of restricting its movement in solid wastes or soil. Equilibrium experiments were performed to evaluate the removal efficiency of fly ash. The adsorption experiments were undertaken using fly ash treated at three different pH levels and with three different temperatures. The results indicate that although phenol can be removed from water, this depends markedly on the temperature and pH value of the treatment solution employed.

Stabilization Method

This study presents an innovative stabilization method of fly ash derived from co-combustion of municipal solid waste and sewage sludge. Bottom ash, obtained from the same process, is used as a stabilizing agent. The stabilization method involved the use of two other components—flue gas desulfurization residues and coal fly ash. Leaching tests were performed on stabilized samples, aged in a laboratory at different times. The results reveal the reduction of the concentrations of heavy metals, particularly Zn and Pb about two orders of magnitude lower with respect to fly ash. The immobilization of heavy metals on the solid material mainly depends on three factors—the amount of used ash, the concentrations of Zn and Pb in as-received fly ash and the pH of the solution of the final materials. The inert powder, obtained after the stabilization, is a new eco-material, that is promising to be used as filler in new sustainable composite materials.

Waste Coal

This paper reviews the pathways that large volume utility wastes can take which can cause environmental effects. Potential interactions of the environment with land-disposed utility wastes include: (1) effects on local air quality, (2) efforts on soils and vegetation, (3) phytotoxicity, (4) groundwater effeccts, (5) effects on surface waters, and (6) disposal site washout. Both natural and engineered mitigating mechanisms are reviewed.
