| Abstract: | The sorption capacity of coal ash will greatly increase when modified by waste sulfuric acid.Experiments are conducted to treat biochemical nitrobenzene wastewater by using modified coal ash,in which the influences of the dosage,pH value,absorption time on chromaticity removal are investigated and the mechanism is analyzed.The use of modified coal ash to treat nitrobenzene wastewater is of great economic significance,in which the rubbish is used to harness rubbish. |
