Abstract

A sensitive extraction-spectrophotometric method for microdetermination of boron with Methylene Blue (MB) has been investigated and firstly applied to the determination of trace boron in sodium metal (coolant of Fast Breeding Reactor) and UF6 (nuclear fuel). 0.5μg/g of boron in sodium metal and UF6 are determined with a relative error ±4% and ±3%, respectively. Six samples of UF6 can be analyzed in 2hr with satisfactory results.
