Description
技术领域
本发明涉及吸附分离技术领域,更具体的说是涉及一种磁性铊离子印迹聚合物及其制备方法和其在废液中一价铊分离上的应用。
背景技术
铊(TI)是一种剧毒的稀有重金属元素。早在18世纪,TI已经在众多领域得到了广泛的应用。TI的来源较为广泛。其中,有色金属冶炼厂、燃煤火力发电厂和水泥厂是人类活动中铊污染物的主要来源。TI的所有化合物都是剧毒物质,对哺乳动物的毒性远大于Hg、Pb、As等重金属。其中,铊的低价态卤素化合物具有其较高的挥发性、水溶性、剧毒性和传播能力,对于人体的危害极大。随着含铊矿物和煤炭的开采量增加,铊排放量呈逐年上升趋势,导致铊污染越来越严重。我国每年的铅锌生产量超过600t,生产过程中会产生大量含TI废水,对水体的污染极大。TI多以TI(I)的形式存在于水相中,在水中具有良好的流动性和稳定性。目前对于含铊废水治理技术,主要包括化学沉淀法、吸附法、离子交换法、生物制剂法、萃取法等。但多数去除方法由于其成本较高、选择性低等缺点,如普通萃取法,不仅成本较高,毒性大,易挥发,对废液中TI(I)的提取率较低,且萃取后的废液难处理,处理不当容易对环境造成二次污染。所以,金属离子的识别和选择性研究仍是当前水体金属离子污染分析中一大挑战。
离子印迹聚合物,是以某一特定的目标离子为模板,通过将目标金属离子与功能单体聚合和洗脱等,在聚合物内部留下与金属离子形状、大小以及功能团均互补的三维印迹腔穴,从而制备对该目标离子具有特异选择性的聚合物。离子印迹材料具有制备简单、结构稳定、识别性强、吸附速率快、吸附容量大和易回收等特点,在重离子分离领域受到广泛的关注。虽然离子印迹材料拥有较大比表面积和吸附容量,但由于其尺寸较小,废液难以实现分离。限制其应用范围。于是,出现了磁性离子印迹技术。磁性离子印迹聚合物由离子印迹聚合物和磁性物质组成,它不仅具备离子印迹聚合物的选择性吸附的特点,能够快速从复杂的体系中分离出目标分子,还由于其存在的磁性材料使其在外加磁场作用下易于样品分离。
发明内容
有鉴于此,本发明针对上述冶炼废液中铊分离技术存在的不足,提出了一种使用磁性TI(I)离子印迹聚合物将废液中的一价TI离子选择性萃取分离的方法。该磁性TI(I)离子印迹聚合物不仅对TI(I)具有高度选择性,同时,它的磁性使得在使用后易于分离。减少了后续洗脱过程中有机溶剂的使用量,在环保的同时减少有机溶剂消耗,降低了成本。
为了达到上述目的,本发明采用如下技术方案:
一种磁性铊离子印迹聚合物的制备方法,包括以下步骤:
步骤1,将TI(I)离子模板溶液与磁性纳米颗粒均匀混合得混合液A;
步骤2,向步骤1得到的混合液A中加入功能单体、引发剂和交联剂;
步骤3,将步骤2得到的混合液B经过超声处理后置于40-80℃的惰性气氛下进行聚合反应,得到带有TI(I)模板离子的磁性离子印迹聚合物前驱体;
步骤4,依次使用清洗剂、洗脱剂对带有TI(I)模板离子的磁性离子印迹聚合物前驱体进行清洗,然后用去离子水冲洗直至上层清液呈中性,干燥后即得到磁性铊离子印迹聚合物。
功能单体的作用主要是与模板离子通过离子键、配价键等作用形成高稳定性聚合物,从而增强对目标离子的吸附能力就会越强;交联剂的主要作用是在铊离子印迹聚合物的合成过程中通过使功能单体与模板离子发生反应更好的将其固定在模板离子周围的特定位置上,从而形成交联度和刚性很强的聚合物。惰性气体主要是阻隔磁性物质中的MFe2O4与空气的接触。
优选的,步骤1中磁性纳米颗粒为改性MFe2O4或MWCNT-MFe2O4(M=Fe2+、Mn2+、Co2+、Ni2+)磁性纳米颗粒,其制备方法为:在三口瓶中,将FeCl3·6H2O和MSO4·nH2O或FeCl3·6H2O、MSO4·nH2O、MWCNT溶于蒸馏水中,瓶中持续性通入惰性气体,然后加入氨水,使溶液pH保持在8-10,在60-90℃下持续搅拌后在150-250℃下反应8-12h,然后乙醇清洗,用强磁铁收集,最后真空干燥后使用亚麻酸进行改性得到改性MFe2O4或MWCNT-MFe2O4(M=Fe2+、Mn2+、Co2+、Ni2+)磁性纳米颗粒。
采用上述技术方案的有益效果:采用油酸改性的目的是在不影响其磁性的情况下隔绝其与空气或目标溶液中的其他氧化性较强的离子发生反应,防止其被空气中的氧气或目标溶液中的氧化性物质氧化,破坏其磁性。在后续重复使用过程中可再次使用油酸改性保护其磁性。
优选的,将TlCl与溶剂按质量体积之比为1g:50-100ml混合配置TI(I)离子模板溶液;所述溶剂为乙醇、乙腈、甲苯、异丙醇、甲醇中的一种或几种。
优选的,步骤1中TI(I)离子模板溶液与磁性纳米颗粒的质量比为1:80-120。
优选的,步骤2中功能单体选自甲基丙烯酸(MAA)、丙烯酰胺(AM)、1-乙基咪唑、2-烯丙硫基烟酸、2-乙酰氨基丙烯酸中的一种或几种;引发剂选自偶氮二异丁腈(AIBN)或过氧化苯甲酰(BPO);交联剂选自二甲基丙烯酸乙二醇酯(EGDMA)、二乙烯基苯-80(DVB-80)或乙二醇二甲基丙烯酸中的一种;所述TI(I)离子模板溶液与功能单体和交联剂的摩尔比为1:(1-5):(4-30);引发剂和交联剂的摩尔比为(5-10):1。
优选的,步骤3中超声处理时间为30-60min,聚合反应时间为8-12h。
优选的,所述步骤4中清洗剂选自1%甲醇溶液、1%-5%的盐酸溶液或乙二胺中的一种;所述洗脱剂为盐酸溶液、硝酸溶液或乙醇与醋酸以任意比例混合的混合液。
本发明还提供了根据上述方法制备得到的磁性铊离子印迹聚合物在废液中一价铊分离上的应用。
优选的,将所述磁性铊离子印迹聚合物直接投入目标废液中处理废水20-30min,后使用永磁体将磁性铊离子印迹聚合物回收,回收后使用蒸馏水清洗掉表面多余的废液,烘干后再依次使用洗脱剂、蒸馏水清洗掉吸附在磁性铊离子印迹聚合物上的目标TI离子,烘干后重复使用。
经由上述的技术方案可知,与现有技术相比,本发明具有以下有益效果:
(1)选择性高:磁性离子印迹聚合物以目标离子为模板制备而成。相较于传统去除方法,如活性炭吸附,或P204萃取技术等在重金属离子分离领域广泛使用的方法相比,磁性铊离子印迹聚合物对TI(I)离子识别度非常高。在环境复杂的废液中,可以有效地清除其他金属离子的干扰。
(2)分离度高:利用外加磁场可迅速将磁性铊离子印迹聚合物(MIIPs)与废液分离。
(3)处理效果好:选用的磁性纳米颗粒比表面积大,可以对废液中的目标离子有效吸附。
(4)便宜易得,且操作成本较低:材料制作成本低,且由于其磁性特点,可利用外加磁场迅速从水体中分离,减少过滤分离步骤时间和资金成本。
(5)绿色环保:可重复使用,由于其磁性特征简化了后续与样品溶液的分离步骤,减少了有机溶剂的使用消耗,且提升实验人员在实验操作过程中的健康保障。
