Determination of Ag in Lead Ore and Zinc Ore by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) with Kinetic Energy Discrimination
The practicability of the method was evaluated by optimizing the Nebulizer Gas Flow,collision gas flow,detection limit,accuracy and precision.Inductively Coupled Plasma Mass Spectrometry with Kinetic Energy Discrimination can eliminate interference effectively.The method detection limit were 0.011 μg/g.The relative error of GBW07235,GBW07236 and GBW07237 ranged from 0.7%to 2.0%.The relative stand-ard deviation(RSD,n =8)ranged from1.6%-3.4%.The method is simple and convenient.It can satisfy the determination of Ag in lead ore and zinc ore.
