Interferences in the atomic-absorption: determination of silicon.
The following substances have been investigated with regard to their interfering effect in the determination of silicon by AAS: HCl, HNO(3), H(2)SO(4), Na(+), K(+), Cs(+), A1(3+), Ni(2+), Mn(2+), Fe(3+), V(5+), Mg(2+), Cu(2+), Zn(2+) and Ti(4+). Some ternary systems with aluminium have been studied to examine the additive effects. Most of the interferents enhance the silicon absorption; only nickel and the acids exert depressive effects; the interference of copper and zinc is negligible.
