A new method for spectrophotometric determination of boron with rutin (in Japanese)
A new photometric method for determining boron with rutin as a color reagent is proposed. The sample solution is evaporated with proper amounts of hydrochloric and oxalic acids and rutin reagent solutions. Then, the dried residue is dissolved with acetone, and absorbance of the solution tbus obtained is measured at 440 m mu . Effects of the concentrations of hydrochloric and oxalic acids and of rutin, and drying conditions such as temperature, duration of heating, and vessels for evaporation are examined, respectively. It is found that Beer's law is obeyed over a range of 0.00--0.30 ppm of boron. The proposed new photometric method is applied to the determination of trace amounts of boron in samples of reactor graphite. (auth)
