Because in the pulverized coal ash adding water pollutant has the strong adsorbability, not only may achieve with the pulverized coal ash processing waste water by governs the waste goal waste, moreover the disposal cost is inexpensive. this article takes the adsorption material with the pulverized coal ash, the methyl orange is an adsorbate, uses the pulverized coal ash to carry on the adsorption to it. Through a series of balanced experiments, the use spectrophotometric method track adsorption process density change, under the computation related conditions adsorptive capacity, the definite adsorptive capacity and the pulverized coal ash particle size, the time, the pulverized coal ash throws between the increment, the temperature, the pH value adsorption rule, then appraisal pulverized coal ash adsorption characteristic.
