“…The S02 produced was oxidized to SO3 which reacted with the H20 to yield sulfuric acid, which was determined alkalimetrically. Ishii, Hirose, Mori, and Kato (129) determined hydrogen in organic liquids by scattering of thermal neutrons. Ishii, Mori, and Hirose, (130) improved the method with reference to collimation of the neutron beam and use of a graphite reflector.…”
