外文摘要：Abrupt heavy mental pollution occurred more and more frequently in recent years,which threatened the wealth se-curity and human health.For risk-assessment studies and follow-up remediation projects,developing a method for rapid field detection to monitor the emergency accident was necessary.Aiming at the demand for rapid field detection,in this the-sis,the portable heavy metal analyzer was applied to detect Cu,Cd,Pb,Zn,Hg,As,Tl,Mn,Ag,Sb,Ni,Cr,Fe and Co in wa-ter,which provided significant accuracy,with recovery rate of 84.0％-117％,and relative standard deviation of less than 5％,and low determination limits in the range of 0.14 μg/L-1.47 μg/L for stripping voltammetry,4.8 µg/L-23.5 μg/L for colorimetric method.Experimental results showed high reliability and strong field application capacity to meet the needs of field applications with significant advantages.
