Cloud-Point Extraction/Graphite Furnace Atomic Absorption Spectrometry for the Determination of Trace Rhodium in Water Samples

摘要

Due to its unique physicochemical properties, rhodium is widely used in standard thermocouples, electroplating, the electronics industry, for cancer treatment, and as a catalyst in the chemical and automobile industries. The consumption of rhodium in the production of autocatalysts accounts for more than 80% of the world production of the metal. Increasing use of catalysts in automobiles results in emission of rhodium into the environment. Therefore, methods for the accurate determination of rhodium in environmental and biological samples are critical to assess future risk to the ecosystem and human health.
