“…I. stream 0.10 M in H202, and both streams 0.10 M in HISO, and of equal concentration, within the range 0.015-0.020 M, in 1 or 2, unless stated otherwise. When using the TiC1,-NH20H method (14), the reaction conditions were as for the TiC1,-H,0, work except that the H,O, in the oxidizing stream was replaced with 1.0 M NH,OH*HCl. When employing the TiC1,-Na,S20x system, the reaction conditions employed first were as for the TiC1,-H?02 work, i.e., with the reaction mixture at pH ca.…”
