水体中重金属污染越来越受到人们的关注与重视,急需开发高效低耗、利于推广的便携式的水质检测技术,帮助地质及环境领域的工作者现场获取实验数据,对污染区域及时做出准确的水体环境评价,有助于水体污染的预防与治理工作。采用无外接电源的富集装置,在pH 4的条件下以S-930螯合树脂捕集水体中的重金属,经抽滤制得均匀薄膜样,再使用手持式XRF现场分析水体中Mn,Fe,Ni,Cu,Zn和Pb等6种重金属元素。各元素标准曲线的相关性r>0.992,方法检出限为5.8~18.6μg·L-1,精确度基本控制在15%RSD以内。方法应用于我国东北某矿区周边采集的20余个地表/下水样品的现场分析,检测结果与实验室ICP-MS结果进行了对比:两种方法的Pb,Ni和Cu一致性良好;Zn和Mn含量高的样品,ICP-MS结果高于现场XRF结果,可能因溶液中存在细微悬浮颗粒引起,但总体趋势一致;两种方法对水质类型的总体判断结果一致。本法使用的富集和测量装置体积小、重量轻、便于携带,不使用外接电源,可在12h内现场完成10个水体样品的采集、前处理操作、结果获取及数据处理等工作,避免实验室分析方法检测工作中存在的交通运输、测试周期长、测试成本高等问题,基本具备了在偏远地区现场分析水体中六种重金属元素、评定水质的能力,具有较好的推广应用前景。
