【摘要】 自然环境是人类赖以生存的物质基础。在长期的历史发展过程中,人类通过生产活动,不断从环境中获取物质、能量和信息,创造了丰富的物质文明和精神文明,最后又将转化了的物质和精神产物排入环境,其中也包括大量的污染物。尤其是工业革命以来,伴随工业化而来的环境污染日趋严重,并已经严重影响到经济、社会的可持续发展。目前,世界各国对环境污染物的排放指标都有严格的限制和要求,环境监测的力度大大加强。其中对化学性有毒有害物质的监测就是一项重要的指标。Pb(Ⅱ)、Cd(Ⅱ)、Hg(Ⅱ)、Cr(Ⅵ)等重金属和挥发酚类等物质都属于污染环境的重要毒物。其中重金属污染还可以在生物体内蓄积、转移,造成食物链的污染,而最终对人类产生危害。流动注射分析法是二十世纪七十年代发展起来的一种分析技术,已经得到国际分析化学界广泛重视。流动注射分析技术具有分析速度快、准确度和精密度高、试剂和试样的消耗量少、设备价廉且操作简单、通用性强、可以与多种检测仪器联用等一系列优点。分光光度法是最早与流动注射联用的检测方法,该方法简便,仪器结构简单、价格低廉,几乎所有溶液中的光度分析都可以设计成流动注射分析,目前仍然是应用最广泛的检测方法,尤其是在水质自动监测分析中更是占有重要的位置。流动注射在线分离、预富集技术是该项分析技术中的重要内容,也是流动注射技术发展的前沿,近年来备受人们关注。常用流动注射在线分离、预富集方法有:在线溶剂萃取;在线沉淀、共沉淀分离;在线预柱吸附分离、富集;更多还原

【Abstract】 Natural environment is the material base on which human beings rely for existence. During the long historical development, human beings have been continuously obtaining material, energy and information from the environment by productive activities to create rich material as well as cultural and ethical civilization and discharge material and ethical products finally transferred, including many pollutants, into the environment. Especially since the industrial revolution, environmental pollution resulted from industrialization has become more and more severe, which has greatly hampered the sustainable development of economy and society. Recently, all the countries worldwide have set strict restrictions and requirements on the discharge guide lines of pollutants, and also greatly strengthened the power of environmental monitoring, in which monitoring on poisonous and harmful chemical materials is one important standard. Heavy metals such as Pb(Ⅱ), Cd(Ⅱ), Hg(Ⅱ), Cr(Ⅵ) and volatile phenol all belong to serious poisonous pollutants, among which heavy metal pollution might store and transfer in organisms, causing pollution of food chain and finally doing harm to human beings.Flow injection analysis, as a kind of analysis technique developed from 1970s, has received wide attention in international analytical chemistry circle. Flow injection analysis owns series of advantages such as high analytical speed, high accuracy and precision, low cost of reagent and sample, cheap equipment and simple operation, high generality as well as capability of combined use with many kinds of更多还原
