摘要 使用水热合成法制备球状锌铝层状氢氧化物(Zn/Al-LDH),并通过超声将不同含量的球状Zn/Al-LDH负载在壳聚糖海绵上,研究其对洗涤废水中微纤维的吸附去除效果。通过扫描电子显微镜、比表面积吸附脱附仪等对海绵进行了表征,探究不同规格的海绵对微纤维的吸附能力,结果表明:负载不同含量的球状Zn/Al-LDH海绵对洗涤废水中的微纤维具有优异的吸附性能,其中负载球状Zn/Al-LDH与壳聚糖的质量比为1∶50时海绵的比表面积最大,为105.39 m2 /g,吸附效果最好,最大吸附效率可达42.06%,最大吸附量可达63.09 mg/g。

Abstract: This paper uses hydrothermal synthesis of spherical zinc-aluminum layered hydroxide (Zn/Al-LDH), and ultrasonically loads different contents of spherical Zn/Al-LDH on chitosan sponge to study its effect on microfibers in washing wastewater. Adsorption removal effect. The sponge was characterized by scanning electron microscopy, specific surface area adsorption and desorption instrument, etc., and the adsorption capacity of different specifications of sponges on microfibers was explored. The fiber has excellent adsorption performance. The specific surface area is the largest when the mass ratio of the loaded spherical Zn/Al-LDH to chitosan is 1∶50, which is 105.39 m2 /g, the adsorption effect is the best, and the maximum adsorption efficiency can reach 42.06%. The maximum adsorption capacity can reach 63.09 mg/g.
