【摘要】：采用堿改性方法改性粉煤灰,通過單因素試驗(yàn)處理含鉻廢水,并對(duì)操作條件進(jìn)行選擇和優(yōu)化,單因素試驗(yàn)表明當(dāng)投灰量60 g/L,pH值14,吸附時(shí)間60 min,吸附溫度為20℃,Cr~(6+)初始濃度為40μg/m L的條件下,Cr~(6+)去除率可達(dá)92.72%。吸附機(jī)理試驗(yàn)表明堿改性粉煤灰吸附含鉻廢水的過程符合Freundlich吸附等溫方程。
[Abstract]:Fly ash was modified by alkali modification method, and the operating conditions were selected and optimized by single factor test. The single factor test showed that the removal rate of Cr~ (6) could reach 92.72% when the ash dosage was 60 g / L, the pH value was 14, the adsorption time was 60 min, adsorption temperature was 20 鈩，
