  • 摘要: 以活性焦为吸附剂,采用静态吸附实验考察活性焦对PCP-Na模拟废水的吸附性能,研究了反应时间、温度、pH值、活性焦用量对吸附效果的影响,采用急性毒性法评价吸附前后废水急性毒性的变化.结果表明,在原始pH下,温度40 ℃,活性焦用量4 g·L-1,反应时间180 min时,废水中PCP-Na的浓度由100 mg·L-1降为2.92 mg·L-1,去除率97.07%.吸附后废水的急性毒性下降99.09%.PCP-Na在活性焦表面的吸附是拟二级反应,吸附速率常数为2.52×10-2 g·mg-1·min-1,其吸附行为可用Langmuir等温线模型进行描述;热力学计算结果表明吸附反应是自发和吸热过程.
    Abstract: Sodium pentachlorophenate (PCP-Na) wastewater is highly toxic and poorly degradable. Static adsorption test was conducted to investigate the adsorption properties of activated coke (AC) for treatment of PCP-Na simulated wastewater. The effect of contact time, temperature, pH and activated coke dosage on PCP-Na removal was studied. Under the conditions of initial pH and 40 ℃, the concentration of PCP-Na decreased from 100 to 2.92 mg·L-1 after 180 min of contact with the AC dosage of 4g·L-1, The acute toxicity was reduced by 99.09% after adsorption. The adsorption kinetics of PCP-Na on AC was coincident with pseudo second-order and the rate constant was 2.52×10-2 g·mg-1·min-1. The Langmuir isotherm can be used to describe the adsorption process. The thermodynamic analytical results indicated that the adsorption was spontaneous and endothermic.
