氯碱固废资源化利用处理染料废水应用研究
Resource utilization of chlor-alkali solid waste and its adsorption performance on Congo red
以氯碱工业废料中盐泥和芒硝为原料,通过常压酸化法,在98℃、钙镁离子摩尔比为1∶1、pH为1条件下,反应4 h,成功制备出绿色功能材料半水硫酸钙晶须(CSHW)。探究了CSHW对阴离子染料刚果红(CR)的吸附性能。试验表明,当模拟染料废水CR初始浓度为100 mg/L、pH为7、吸附剂投加量为4 g/L、吸附时间为120 min时,CR去除率可达94.82%。CSHW对CR的吸附行为更符合Langmuir吸附模型和准二级动力学模型,吸附行为以单层吸附为主,吸附过程为自发吸热过程。CSHW对CR优异的吸附性能归因于氢键和静电吸附作用。本研究为工业固废资源化利用及染料废水治理提供了技术参考。
Calcium sulfate hemihydrate whiskers (CSHW),a green functional material,was successfully synthesized through atmospheric acidification method utilizing chlor-alkali brine sludge and Glauber’s salt as raw materials.The preparation conditions were at 98℃,calcium and magnesium ion molar ratio of 1∶1,pH=1,and the reaction was 4 h.When the simulated dye wastewater with an initial CR concentration of 100 mg/L and a pH of 7 was treated using an adsorbent dosage of 4 g/L,the CR removal rate reached 94.82% after 120 minutes pseudo-second-order kinetic model and the Langmuir isotherm adsorption model.The adsorption process was predominantly governed by monolayer adsorption,exhibiting spontaneous and endothermic characteristics.The adsorption mechanism of CSHW on CR can be attributed to the physicochemical effects such as hydrogen bonding and electrostatic adsorption.This study offers a technical reference for the resource utilization of industrial solid waste and the treatment of dye wastewater.
