Automated Flow Injection Coupled with ICP-MS for the Online Determination of Trace Silver in Seawater

Zuhao Zhu;Airong Zheng
January 1st 2017

Measuring silver (Ag) in seawater is challenging. A sensitive analytical procedure, using a simple automated flow injection system online coupled with ICP-MS, which is easy to be installed in an ordinary ICP-MS lab, is reported in this paper. Parameters including flow rate and duration, and the effects of the pH and dissolved organic matter (DOM) concentration and salinity were investigated. The standard addition method was used for the quantification. The linear range of the method was up to 1000 ng kg-1. For samples with various salinities the RSDs were
