摘要:

The technique of precipitation from homogeneous solution by photochemical action has been successfully applied to the determination of La, Ba, and In. Precipitation is accomplished through the photoreduction of IO4−to produce the insoluble iodates. In the case of Zr and Ti, the more soluble periodate is coprecipitated with the iodate and the method is not successful. Cu and Ni cannot be estimated by this method.
