称取0.5g的聚多巴胺纳米微球,用50mL去离子水溶解配置成溶液,用盐酸将pH调整至2,随后超声50min。将15mL的2mol·L-1高锰酸钾(KMnO4)溶液加入至聚多巴胺纳米微球溶液中,磁力搅拌器下反应5h,离心得到黑色沉淀,放入鼓风干燥箱中干燥25h。
实施例4
对实施例1合成的聚多巴胺纳米微球、聚多巴胺纳米微球-MnO2分别进行暗室条件下对水溶液中的染料分子罗丹明B(RhB)吸附去除,并分别以水溶液中的罗丹明B染料分子的吸附去除后溶液对紫外光的特性吸收作为判断罗丹明B分子的存在依据,用于确定在暗室条件下吸附剂聚多巴胺纳米微球、聚多巴胺纳米微球-MnO2对罗丹明B染料的吸附去除能力。
具体步骤如下:
将10mg的吸附剂聚多巴胺纳米微球、聚多巴胺纳米微球-MnO2分别加入50mL浓度为10.0mg/L的罗丹明B(RhB)水溶液中作为实验组,并取同样体积同浓度的罗丹明B(RhB)水溶液组为对照组。在暗室中,搅拌实验组的罗丹明B(RhB)水溶液的到悬浮物,选择不同的时间取出5mL溶液进行离心分离,得到澄清上层溶液进行UV测试。实验组罗丹明B(RhB)水溶液在暗室中分别经过15min、30min、45min、60min、120min的搅拌反应后,如图1所示,罗丹明B(RhB)的特征吸收明显降低,表明大部分染料分子罗丹明B(RhB)已经被吸附剂吸附去除。其中,240min吸附剂聚多巴胺纳米微球对罗丹明B(RhB)的吸附去除率是67.2%,吸附剂聚多巴胺纳米微球-MnO2的吸附去除率为91.7%(图2)。不加入任何吸附剂的对照组的罗丹明B(RhB)水溶液在暗室条件下搅拌反应48h后,罗丹明B(RhB)降解率非常低,表明罗丹明B(RhB)仅仅通过暗室条件下不加入任何吸附剂时实现降解去除是不可能实现的。
