摘要
以硫代乙酰胺,氯化镉,钼酸钠和有机大分子六元瓜环(cucunbit[6]uril,Q[6])为原料,采用水热法在200℃反应24小时合成CdS-MoS_(2)和Q[6]/CdS-MoS_(2)。利用FT-IR、XRD、XPS、SEM和UV-Vis等手段对产物结构、形貌和光学等性质进行表征,并考察CdS-MoS_(2)和Q[6]/CdS-MoS_(2)复合吸附剂对次甲基蓝的吸附作用。结果表明,CdS-MoS_(2)和Q[6]/CdS-MoS_(2)形成了花团状形貌,使其表面积较大,吸附面积增加,对次甲基蓝表现出较高的吸附量和脱色率,吸附符合准二级动力学模型。
CdS-MoS,and Q[6]/CdS-MoS,were synthesized from thioacetamide,cadmium chloride,sodium molybdate and cucurbit[6]uril(Q[6])by hydrothermal method at 200 C for 24 hours.The structure,morphology and optical properties of the products were characterized by FT-IR,XRD,XPS,SEM and UV-Vis,and the adsorption of methylene blue on CdS-MoS_(2)and Q[6]/CdS-MoS_(2)composite adsorbent was investigated.The results showed that the CdS-MoS_(2)and Q[6]/CdS-MoS_(2)particles formed flower clusters with petal like leaves,and the particle surface area was larger,which increased the adsorption area,and showed a higher de-colorization rate and adsorption capacity for methylene blue,and the adsorption accorded with the pseudo-second-order kinetic model.
