摘要
以往,少见浒苔对废水中Pb2+吸附的研究报道。通过浒苔对铅的吸附试验,研究了浒苔对水溶液中Pb2+的吸附性能及影响因素,考察了pH值、Pb2+初始浓度、吸附时间、吸附剂用量等因素对吸附效果的影响。结果表明:浒苔对Pb2+有较强的吸附能力;当含Pb2+废水pH值为4.0时,以1 g/L浒苔处理50 mg/L Pb2+废水,吸附效率可达82%;吸附过程符合Langmuir和Freundlich等温吸附模型。
The adsorption capability of Enteromorpha Prolifera for Pb2+ in wastewater as well as the factors influencing the adsorption efficiency was examined by conducting adsorption tests.The effects of pH value and initial Pb2+ concentration of wastewater as well as the adsorption time and adsorbent dosage on the adsorption efficiency were investigated.Result shows that Enteromorpha Prolifera has good absorption capability for Pb2+,and an adsorptive efficiency of 82% can be acquired when 1.0 g/L adsorbent is used to treat wastewater with a pH of 4.0 and Pb2+ concentration of 50 mg/L.Besides,the adsorption process of Pb2+ in wastewater by Enteromorpha Prolifera can be well described with the Langmuir and Freundlich isotherm models.
