摘　　要：以菱角壳为原料,通过微波改性获得改性菱角壳,来吸附废水中的Cr(Ⅵ),当微波功率为700 W,微波改性时间为120 s,含Cr(Ⅵ)废水中Cr(Ⅵ)的浓度为10 mg/L,改性菱角壳投加量为16 g/L,吸附处理时间为90 min,温度为35℃,水样的p H为2时,处理效率可达99.42%。The water chestnut shell was used as raw material to adsorb Cr(Ⅵ) in wastewater by microwave modification.When the microwave power was 700 W,the microwave time was 120 S,the concentration of Cr(Ⅵ) in the wastewater was 10 mg/L,the dosage was 16 g/L,the adsorption time was 90 min,the temperature was 35℃,and the p H value of the water sample was 2,the treatment efficiency could reach 99. 42%.
