Atomic absorption method for determining micromolar quantities of thiols

Determination of 1,2-diols by indirect atomic absorption with digested lead periodate

“…Recently, indirect atomic absorption methods were employed for the determination of aliphatic secondary amines, aldehydes, and thiols (8)(9)(10). In each of these indirect atomic absorption spectrophotometry (IAAS) methods, a metallic precipitate formed with the analyte or with the product was incorporated in the final procedure before filtration and finally digested for analysis.…”

Functional group analysis

“…Another separation method involves the precipitation of the thiol as the silver salt with alcoholic silver nitrate. After isolation of the precipitate, it is converted to silver ion and analyzed by atomic absorption spectroscopy (54).…”
