Keywords Coal y ash · Adsorbent · Dye · Geopolymer · Water remediation · Pollutants 1 Introduction Coal y ash (CFA), also known as pulverized fuel ash, is nely divided mineral residue obtained from powdered coal combustion in thermal power plants. During the process of burning, temperature may go above 1600 °C and most of

 — Water, a major fluid contained in coal, is almost certainly super-heated if the microwave energy is high enough. The rapid vaporization of water will form local stress in the pores which will promote the fracture initiation [34], [35], [36]. Therefore, microwave irradiation induces more fractures and increases cleat apertures in the coal sample ...

 — The zeta potential of the coal particles in the CWS was determined by ZEN3690 Zetasizer (Malvern Instruments Corp., British). Dilute coal-water suspensions of 0.1 g coal powder in 50 ml water with and without dispersants were shaken in …

 — When the coal powder is mixed in, hydrophilic minerals on the coal surface interact with the water in the water cores, causing some of the coal particles to enter the reverse micelles. As a result of this, the hydrophobic chain of Tween 80 reaches into the oil phase and the water core becomes a hydrated film on the surface of the coal particles ...

 — The Powder River Basin coal-bed methane boom in the early 2000s stirred controversies over land rights, mineral rights, environmental stewardship, the disposal of water and—at every turn—politics. Now, few of the 29,000 wells drilled produce much gas and around 3,000 wells are abandoned and left to the state to clean up.
