Abstract

A method by microwave digestion-plasma torch atomic emission spectrometry was developed for the determination of Cu, Cd, and Pb in Scutellaria indica. The samples of Scutellaria indica were digested by microwave. The heavy metal ion was enriched and extracted by cloud point extraction technology, which used 8-hydroxyquinoline as a chelating agent and Trion X-110 as an extractant. The determination of Cu, Cd, and Pb was analyzed by microwave digestion-plasma torch atomic emission spectrometry under optimal experimental conditions. The results show that the method provided curated measurements, good repeatability, good linear relationships, and high recoveries. A new method for the determination of heavy metals in traditional Chinese medicine and related products was established, which is environmentally friendly and convenient.
