Determination of lead at ultratrace levels
Lead is a toxic heavy metal harmful to our digestive,immune and nervous systems following ingestion or inhalation.Therefore, the development of new methodologies to detect lead even at ultratrace levels is necessary.
A compact trap and atomizer device to pre-concentrate lead and determine ultratrace levels has been developed in the past.However,a strong interference of bismuth during the lead pre-concentration procedure is observed.To explain the bismuth interference,Jan Kratzerand colleagues from theInstitute of Analytical 新利手机客户端Chemistry of the ASCR,Czech Republic,quantify the trapping and volatilization efficiency of lead with a new radiotracer employing a Pb radioactive indicator.This recent study improves the understandings of the currently developed quarz trap atomizer device and demonstrates that the radiotracer approach is a powerful tool in method development.
