【摘要】 采用低饱和共沉淀法制得锌/铜/铝类水滑石化合物(Zn5Cu Al2(OH)16CO3·x H2O),在450℃焙烧得焙烧物,通过XRD,FT-IR,SEM和TG-DSC等手段对样品的结构、形貌和热稳定性进行了分析。将其焙烧物用于吸附模拟印染废水中的阴离子染料活性艳橙,结果表明,p H值在2~9,经吸附90 min,其对印染废水的吸附性能最佳,染料去除率达96%以上。更多还原

【Abstract】 The Zn / Cu / Al hydrotalcite-like compounds are synthesized by low saturated co-precipitated method.The structure,morphology and thermal stability of the sample is characterized by XRD,FT-IR,SEM and TG-DSC measurements.The absorptive properties of its roast on anionic dye reactive brilliant orange are studied in simulated printing and dyeing wastewater.The results show that when p H value is 2 ~ 9 and absorptive time is 90 minutes,the absorption properties are best.The decolorizing rate of the dye can reach above 96%.更多还原
