中文摘要：
研究了复合金属氧化物（LDO）对模拟废水中十二烷基苯磺酸钠（SDBS）的吸附行为，考察了pH值、温度、吸附时间等因素对SDBS去除的影响，并对吸附后的产物进行了碳酸钠解析试验研究。结果表明：当pH=7，温度为25℃，吸附时间为30min，LDO投加量为0．1g／100mL，SDBS初始浓度为700mg／L时，SDBS的去除率高达95．33％。产物经焙烧再生后重复吸附4次，产物对SDBS的去除率仍可达90．07％，实现了废物的再利用。
英文摘要：
The adsorption behavior of sodium dodecyl benzene sulfurate （SDBS） on layer double oxids（LDO） was studied. The factors affecting the removal of SDBS, such as pH value, temperature, adsorption time and the amount of LDO were investigated, and after adsorption, desorption of products by sodium carbonate was also studied. The results indicated that the removal efficiency of SDBS reached to 95.33% when the pH value was 7, the temperature was 25℃, the adsorption time was 30rain, the amount of LDO was 0.1g/100mL and the original concentration of SDBS was 700mg/L; it was also showed that the removal efficiency of SDBS could reach to 90.07% when the products were utilized four times by calcining, thus the waste can be re-utilized.
