Research on Removal of Chromium (VI) from Waste water on Fly Ash Modified with Alkali Washing and Calcium Oxide Calcining Method

Research on Removal of Chromium (VI) from Waste water on Fly Ash Modified with Alkali Washing and Calcium Oxide Calcining Method

Fly ash was modified by the alkali washing and calcium oxide calcining method The infrared spectrometer and scanning electron microscopy were used to characterize the bond groups and morphology before and after modification fly ash. The dosage, pH, calcined temperature and adsorption time were used...
