    摘要: In a process for producing pure ammonium paratungstate from ammonium tungstate solutions containing tin, sulfide is added to the ammonium tungstate solution in an amount sufficient to form a soluble complex of the sulfide with the tin. The solution is then evaporated to a volume at which essentially all of the tungsten is in the form of insoluble ammonium paratungstate and essentially all of the tin is in the mother liquor in the form of a soluble complex along with other impurities. The solid ammonium paratungstate is then separated from the mother liquor by filtration.

    摘要: For labelling organic or anorganic substances with technetium-99m in the heterogenous phase, an aqueous solution of the substance to be labelled is mixed with a pertechnetate and an aqueous suspension of Sn.sub.2 Fe(CN).sub.6, Sn.sub.3 [Fe(CN).sub.6 ].sub.2, SnS or SnTe and the solution of the labelled substance is separated from the solid phase after completion of the reduction of the pertechnetate. In particular, the reducing agent can be in a vial, in lyophilized or adsorbed form, as appropriate together with the substance to be labeled.

    摘要: A flame resisting agent to be incorporated into an aqueous spinning dope containing chlorine-containing polymer as a main polymer ingredient for improving the flame resistant property of the fiber spun from the spinning dope which includes a stannic oxide hydrate being substantially amorphous with respect to X-ray diffraction and having a bound water in the range of about 0.5 to about 0.7 mole of H.sub.2 O per 1 mole of SnO.sub.2. The flame resisting agent has a superior dispersibility in an aqueous spinning dope containing chlorine-containing polymer as a main polymer ingredient and the aqueous spinning dope in which the flame resisting agent is incorporated has a superior stability, filtering property and spinning property to give a uniform quality of fibers having a durable, superior flame resistant property.
