The minimum detectable concentration of this standard 0. 03mg/L, measured a maximum of 5. 0mg/L. Dilution or concentration measurement range can be extended. A large number of chloride, bromide, iodide, thiosulfate interfere with the determination of silver, but the samples were digested treatment, interference can be eliminated.
