Abstract
Atomic emission spectrometry (AES) was widely used for the determination of silver (Ag) boron (B), molybdenum (Mo) and tin (Sn) in multi-target geochemical surveys, ecological geochemical assessment and International Geochemical Mapping Program (IGCP259/360). The carrier distillation technique based on Alternating Current (AC) arc powder method can effectively reduce the matrix effect and improve the fractionation process of the elements to be measured. By establishing the carrier distillation technique with aluminum oxide (Al2O3), barium carbonate (BaCO3), potassium pyrosulfate (K2S2O7) sodium fluoride (NaF) sulfur (S) ferric oxide (Fe2O3)teflon ([C2F4](n)) as the main components, it was experimentally confirmed that the carrier buffer could well induce the reaction of oxidation, fluoridation and sulfurization. The evaporation process of elements such as Ag, B, germanium (Ge), Mo, and Sn was improved by adjusting a series of physical and chemical reactions to increase the volatilization of the elements to be
