Flow Injection Inductively Coupled Plasma-Mass Spectrometry With Ultrasonic Nebulizer for the Quantification of Trace Elements in Seawater: An Innovative Method Targeting Cadmium, Cobalt, Lead, Manganese, Molybdenum, Tin, Uranium, and Vanadium.

ABSTRACT: The accurate determination of trace elements in seawater is essential for environmental monitoring and the study of oceanic biogeochemical processes. However, traditional analytical techniques often face limitations due to the ultra-trace concentrations of metals and the high salinity of seawater, which introduces significant matrix effects. In this study, a novel flow injection-inductively coupled plasma mass spectrometry (FI-ICP-MS) method coupled with an ultrasonic nebulizer was developed and optimized for the direct quantification of cadmium, cobalt, lead, manganese, molybdenum, tin, uranium, and vanadium in seawater samples. The method was optimized by evaluating the effects of eluent concentration (0.05-0.20% HNO3, with 0.05% selected as the minimum effective value to ensure analyte
