Preparation of Ceramsite from Oil Shale Slag and Its Use in Removing Cu 2 + in Effluent
The random stack of oil shale slag brings a series of ecology and the environment question. This article take the oil shale slag as the primary material, uses the stage elevation of temperature rule to explore oil shale slag ceramsite, and then studies the adsorption on Cu 2+in effluent under the different environmental condition. The test results indicated that the ceramsite may achieve the adsorption equilibrium to Cu 2+adsorption in 900min. with the increment of ceramsite in solution, the Cu 2+adsorption efficiency also increases; when the pH value of solution vary 5 to 6.5, the elimination effect of ceramsite on Cu 2+is obvious. The higher the initial density of Cu 2+in effluent is, the lower its elimination efficiency is, but the adsorption of ceramsite on Cu 2+become higher and higher with the increases of initial density solution. The researches show that it is effective way to use oil shale slag to preparation ceramsite to remove the Cu 2+in effluent.
