Original abstract

An atomic absorption spectrometric method with electrothermal atomization (AAS-ETA) for the determination of arsenic and antimony in high-purity phosphoric acid is described. The determination is based on the rapid generation of arsine and stibine based on reduction with a solution of sodium tetrahydroborate, their absorption in a solution of nickel salt, nitric acid, and bromine, and is suitable for ng g(-1) levels of As and Sb in H3PO4 and other mineral acids.

AAS-ETA pro stanovení arsenu a antimonu ve vysoce čisté kyselině fosforečné je v této práci popsána. Stanovení je založeno na rychlé generaci hydridů As a Sb, které probíhá redukcí tetrahydridoboritanem sodným, jejich absorpci v roztoku nikelnaté soli, kyseliny dusičné a bromu. metoda hje vhodná na stanovení ng/g úrovní těchto prvků v kyselině fosforečné a jiných minerálních kyselin.
