In this study, the preparation of graphene oxide@chitosan (GO@CS) composite beads was investigated via continuous dropping techniques to remove methylene blue (MB)-dye from an aqueous media. The prepared beads were characterized using various techniques before and after the adsorption of MB. The experimental results showed that the adsorption processes fit the kinetic pseudo-second-order and Langmuir isotherm models. Moreover, the GO@CS beads achieve maximum adsorption capacities of 23.26 mg g, which was comparable with other adsorbents in the literature. An important advantage of our adsorbent is that the GO@CS can remove 82.1% of the real sample color within 135 min.
在本研究中，通过连续滴加技术研究了氧化石墨烯@壳聚糖（GO@CS）复合珠的制备，以从水性介质中去除亚甲基蓝（MB）染料。在吸附MB吸附吸附MB之前和之后，使用各种技术对制备的珠子进行了表征。实验结果表明，吸附过程符合动力学准二级和朗缪尔等温线模型。此外，GO@CS珠的最大吸附容量达到23.26 mg/g，这与文献中的其他吸附剂相当。我们吸附剂的一个重要优点是，GO@CS可以在135分钟内去除实际样品中82.1%的颜色。
