Abstract
A study has been made of the experimental conditions, errors, sensitivity, limits of detection and linear response range in the determination of beryllium by AAS in a nitrous oxide-acetylene flame, with aqueous or aqueous organic solutions or MIBK solutions containing the ion-pair [Be(SCN) 2− 4][(R 3NH) 2+ 2]. The interference of Al, Mg, Ti, V, Fe, Ca, Mn, Na, K, SiO 2− 3, PO 3− 4, Cl −, SO 2− 4, F −, ClO − 4, H 2BO − 3 and SCN − has been studied, and methods established for eliminating that of titanium, aluminium, fluoride and silicon.
