Abstract: The trace impurities Cu, Sb, Cr, Au, As, Hg, and P in SiHCl3 were detd. by neutron activation analysis, and a chem. sepn. method was developed. The impurities were bound into a complex by Ph3CCl, evapd. dry, and irradiated in the solid form by a neutron stream of 1.5 × 1013 neutrons/cm2 sec. Because a great amt. of Cl interferes with the identification of P, a parallel activation is carried out by using a Cd filter.
