This paper presents a continuous atmospheric heavy metals monitoring system (AMMS-100) for heavy metals analysis based on X-ray fluorescence (XRF) technology. The AMMS-100 is used to collect the sample automatically with filters and then measure the concentrations of heavy metals by XRF. The accuracy of AMMS-100 for heavy metals analysis has been verified by the standard method. The relative errors, such as Pb and Fe, are lower than 10%. Moreover, the AMMS-100 can be used for long-term continuous monitoring the atmospheric heavy metals under different weather condition. The AMMS-100 described herein presents a continuous system for accurate analysis of atmospheric heavy metals with long-term stability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
