以1.0 mol/L硫酸为改性剂，微波辅助制备酸改性粉煤灰吸附剂。通过SEM、FTIR对粉煤灰形貌及结构进行分析，用分光光度法对其吸附性能进行分析。结果表明，硫酸用量为4 mL/g、微波功率400 W、微波时间8 min时制得的酸改性粉煤灰处理含砷废水效果较好，常温下，当吸附剂用量10 g/L、废水pH值为6、吸附时间30 min时，砷酸根脱除率可达90.29%，比酸改性粉煤灰脱除率提高了5.99%。
以1.0 mol/L硫痠為改性劑，微波輔助製備痠改性粉煤灰吸附劑。通過SEM、FTIR對粉煤灰形貌及結構進行分析，用分光光度法對其吸附性能進行分析。結果錶明，硫痠用量為4 mL/g、微波功率400 W、微波時間8 min時製得的痠改性粉煤灰處理含砷廢水效果較好，常溫下，噹吸附劑用量10 g/L、廢水pH值為6、吸附時間30 min時，砷痠根脫除率可達90.29%，比痠改性粉煤灰脫除率提高瞭5.99%。

Acid modified fly ash was prepared through microwave-assisted with 1.0 mol/L sulfuric acid. The morphology and structure of fly ash was analysed by SEM and FTIR, the adsorption performance of fly ash was analysed by spectrophotometry. The result show that under the modified conditions with the dosage of sulphate acid 4 mL/g, microwave power 400 W, modification time 8 min and with the adsorption conditions of the mass of adsorbent 10 g/L, waste water pH value of 6, adsorption time 30 min, temperature 25℃, the removal rate reach to 90.29%, increase by 5.99%compared with acid modified fly.
