【摘要】 以浓度1.0mol.L-1的硫酸为改性剂,微波辅助制备酸改性粉煤灰吸附剂.通过SEM,FTIR对粉煤灰微观形貌观察及结构表征,用分光光度法对其吸附性能进行分析,结果表明:用硫酸用量为4g.mL-1、微波功率400W、微波时间8min时制得的酸改性粉煤灰来处理含砷废水,常温下,当吸附剂用量10g.L-1,废水pH=6,吸附时间30min时,砷的脱除率可达90.29%.更多还原

【Abstract】 Acid modified fly ash was prepared through microwave-assisted with 1.0 moL·L-1 sulfuric acid.We observe its microstructure by SEM and FTIR to its structure and index and aualyze of the adsorption performance by spectrophotometry.The result shows that:under the modified conditions with the dosage of sulphate acid 4 mL·g-1,microwave power 400 W,modification time 8 min and with the adsorption conditions of the mass of adsorbent 10 g·L-1,waste water pH=6,adsorption time 30 min,temperature 25 ℃,the removal rate of arsenic reach to 90.29%.更多还原
