The B solutions being analyzed are first made alkaline with a solution of NaOH and then evaporated to dryness. They are then used for photometric determinations of B by the carmine method. Optical density is measured at 620 m mu , using a new calibration graph for each series of determinations. For a determination of B in uranyl nitrate the B is separated by distillation, as methyl ester of boric acid, in a quartz apparatus, collecting the methyl borate in an alkali solution. Error of determination of 0.1 to 0.5, gamma amounts to plus or minus 10%. (auth)
