摘要
对于非金属中六价铬的分析,欧盟协调标准是IEC62321-7-2:2017,其样品前处理方式主要有微波消解和超声消解,通过两种前处理方式,用分光光度法测试喷码机油墨中六价铬的含量。结果表明,超声消解的结果稳定性好,符合标准要求。
Spectrophotometry is currently the primary means of hexavalent chromium analysis. For the analysis of hexavalent chromium in non-metals, the EU harmonized standard is IEC 62321-7-2:2017. The sample pretreatment methods mainly include microwave digestion and ultrasonic digestion.In this paper, the content of hexavalent chromium in the ink of the printer is tested by two pretreatment methods. The results show that ultrasonic digestion arestable and meet the standard requirements.
