中文摘要	<正>自然界中的金属与人类的文明发展与经济活动息息相关,各类金属不断地被开发应用到新的制程暨产品中,受到自然界中的生物地质化学循环(Biogeochemical Cycle,又称作生态系统的物质循环)作用的过程中,金属会被释放分布到空、水、土等环境区间乃至生物体内,然而往往因使用人; The metals in the nature are closely related to the progress of human culture and economic activities. Various kinds of metals are continuously being applied to new processes and products.During the effect by biogeochemical cycle,metals were released to environmental compartments,such as air,water,soil,and living organisms.The deficiency in knowledge,poor management,greedy,and bad intention usually leads to serious environmental pollution,eco-environment damage,and human poisoning.Effective analysis of metal concentrations and species during economic activities and eco-environment is an important research and survey subject.Internationally,the establishment of high-tech industrial park has become the major means to simultaneously improve living quality and broaden economic activity.High-tech industry uses metals.It is mandatory to control the distribution of metals in feed,process,product,waste,environment,and the life-cycle. This report is based on our experience with inorganic mass spectrometry focusing on the use of secondary ion mass spectrometry(SIMS)and inductively-coupled mass spectrometry(ICP-MS)in metal analysis of high-tech industrial parks.The report includes(1)The use of SIMS for analyzing impurity in depth and on surface demonstrates the importance of integrating trace metal,depth profile,micro-area,and surface analyses.(2)Survey ambient heavy metals(As,Be,Cd,Dr,Hg,Mn,Ni,and Pb)around industrial parks and compare the findings to stack heavy metals.The results demonstrate that ICP-MS is indispensable to help reveal heavy metal distribution in industrial park ambient air and clarify suspected polluting sources.(3)Research and develop analytical method to determine metal impurities(Na,K,Mg,Ca,Cu,Fe,Mn,Li,and Al)in photoresist.The method uses a novel nitric acid digestion technique to convert photoresist into carbon dioxide and water,followed by ICP-MS analysis of high-purity nitric acid recovery solution.The method performance shows 90%～110% recovery,ppt level detection limit,and good repeatability.The results demonstrate that sample pretreatment is crucial to ICP-MS analysis results.(4)Magnetic nanoparticles modified with polyacrylic acid(MNPs-PAA)were simultaneously synthesized and surface modified with PAA using one-pot chemical coprecipitation method.A hyphenated system consisted of a lab-on-valve subsystem containing a renewable microcolumn coupled to an ICP-MS was developed.
