In this work, GC-MS, ICP-OES, UV-Visible Spectrophotometry were employed to determine the trace concentrations of the above six hazardous substances, and a standard method system for screening primarily, extraction, qualitative and quantitative analyses of the six substances was established and their factors were analyzed. By evaluating the relative standard deviation, recovery, repeatability, limit of detection, linear relation etc., the optimum parameters were given and thus the precision of analysis was equal to or higher than the IEC 62321 standard, meeting the requirement of RoHS.

针对中国电子电气业在遵守RoHS符合性实践中存在的诸多问题，本文采用GC-MS，ICP-OES，UV-Visible分光光度法等，对我国南方和香港地区各类电子电气产品中六种有害物质进行痕量分析，建立了一套标准的六种有害物质初步筛选、萃取、定性、定量分析方法，并对此方法体系的影响因素进行分析，对其相对标准偏差、回复率、再现率、检出限、线性关系等进行评估，得出了优化测试参数，在此条件下其检测的精密度达到或高于国际IEC 62321标准，满足RoHS测试要求。
