|
摘要
水滑石是一种高效的电吸附材料,可用于工业废水中硫代硫酸盐的去除.硫代硫酸盐(S2O2-3)是废水中主要含硫污染物.本研究采用共沉淀法,在泡沫镍基体上成功合成了Ni Al-LDHs,并经煅烧成功转化为Ni Al-LMO电极.NiAl-LMO电极电化学性能稳定,可逆性好,比电容可达577F·g-1.NiAl-LMO电极在外加电压为1. 0 V、p H为7、温度40℃时,对S2O2-3电吸附效率最高达60.9%,施加相反电压后S2O2-3电脱附率达84.9%.本研究为含S2O2-3废水处理提供了新的电吸附电极材料和技术选择.
Hydrotalcite is an efficient electroadsorption material,which can be used to remove thiosulfate from industrial wastewater. Thiosulfate( S2 O2-3)is the main sulfur-containing pollutant in wastewater. In this study,Ni Al-LDHs were successfully synthesized on nickel foam matrix by co-precipitation method and converted into Ni Al-LMO electrode after calcination. The electrochemical performance of Ni Al-LMO electrode is stable,the reversibility is good,and the specific capacitance can reach 577 F·g-1. When the applied voltage is 1. 0 V,p H is 7,and the temperature is 40 ℃,the Ni Al-LMO electrode has the highest electrical adsorption efficiency of 60. 9% for S2 O2-3. After applying the opposite voltage,the S2 O2-3 electrical desorption rate reaches 84.9%. This study provides a new electrode material and technical choice for the treatment of wastewater containing S2 O2-3.
