摘要
以活性污泥为材料,采用不同时间、温度、pH进行吸附重金属Cr6+的研究。实验结果表明,当吸附时间为15min,吸附温度为28℃,吸附pH=7时具有较好吸附效果。在此条件下,当重金属Cr6+浓度为50mg/L,其吸附率可达97.2%。
This paper reports study on the activated sludge was used to adsorb heavy metal Cr(VI) with different time?temperature?pH.The experimental results showed the optimum condition adsorption is that the adsorbent time is at 15min, adsorbent temperature is at 28℃,the adsorbent pH 7.0.When the concentrations of Cr(VI) is at 50mg/L,activated sludge capacities of adsorbed Cr(VI) is 97.2% under the optimum condition adsorption.
