第53卷精细化工中间体硫代酰胺螯合树脂的吸附特性与电镀废水银回收王铭剑1，王康杰1，2，刘耀驰1*（1.中南大学化学化工学院，湖南长沙410083；2.中芯国际集成电路制造有限公司，北京100176）摘要：电镀废水银吸附回收受共存离子及有机物影响。基于胺基聚苯乙烯（APS）制备了一种胺基和芳环协同的硫代酰胺螯合树脂ATMCR，在银吸附特性研究的基础上，将其应用于电镀废水银回收。采用FT-IR、SEM和BET对合成树脂进行了表征。ATMCR对Ag（I）的吸附属于自发、吸热过程，符合拟二级动力学模型，吸附pH为1~2，318K时ATMCR的吸附容量达177.6mg/g。高、低两种浓度电镀废水的处理实践表明，在Cu、Ni和COD共存时，ATMCR的Ag回收率>98%，具备较好的工业应用前景。关键词：硫代酰胺螯合树脂；银；吸附特性；电镀废水中图分类号：TQ424文献标志码：A文章编号：1009-9212（2023）01-0060-07DOI：10.19342/j.cnki.issn.1009-9212.2023.01.013AdsorptionCharacteristicsofThioamideChelatingResinandItsSilverRecoveryfromElectroplatingWastewaterWANGMing-jian1,WANGKang-jie1,2,LIUYao-chi1*(1.SchoolofChemistryandChemicalEngineering,CentralSouthUniversity,Changsha410083,China;2.SMICInternationalIntegratedCircuitManufacturingCo.,Ltd.,Beijing100176,China)Abstract：Theadsorptionandrecoveryofsilverfromelectroplatingwastewaterareaffectedbycoexistingionsandorganicmaterials.AthioamidechelatingresinATMCRbasedonaminepolystyrene(APS)wasprepared.Basedonitssilveradsorptioncharacteristics,ATMCRwasappliedintherecoveryofsilverfromelectroplatingwastewater.ThesynthesizedresinwascharacterizedusingFT-IR,SEMandBET.TheadsorptionofAg(I)byATMCRwasaspontaneousandendothermicprocess,andconformedtothepseudo-second-orderkineticmodel.Itsadsorptioncapacityreached177.6mg/gat318K,andtheoptimalpHrangewasbetween1and2.ATMCRwasappliedtotreatelectroplatingwastewaterwithhighandlowconcentration.ItsrecoveryratesofAgwerehigherthan98%underthecoexistenceofCu,NiandCOD.Thismaterialhasshownagoodindustrialapplicationprospect.Keywords：thioamidechelatingresin;silver;adsorptioncharacteristics;electroplatingwastewater基金项目：湖南省重点领域研发计划（2019KW2031）。作者简介：王铭剑（1978—），男，湖南邵阳人，高...
