ЭЛЕКТРОТЕРМИЧЕСКОЕ АТОМНО-АБСОРБЦИОННОЕ ОПРЕДЕЛЕНИЕ БОРА И ФОСФОРА В КВАРЦЕ IOTA-ST (UNIMIN))

Abstract

An HR CS ETAAS method for B and P determination was developed: P using the PO molecular absorption with NH4F modifier, and B by atomic absorption with Ca modifier. Quantitative formation of BF is impossible due to the mannitol presence in matrix, and the resulting PO molecules overlap its spectrum.
