文摘

A liquid cathode glow discharge-atomic emission spectrometry (LCGD-AES) was constructed. The effects of discharge voltage, solution flow rate and capillary diameter on emission intensity were investigated. The Cu and Pb in ores samples were simultaneously determinate by LCGD-AES. The measurement results of LCGD were well consistent with the reference values of ICP. The LCGD has higher excitation efficiency, lower energy consumption and better discharge stability.
