Spectrophotometric estimation of boron with curcumin after extraction employing 10% 2-ethyl hexane 1, 3-diol (EHD) in CHCl3 has been modified and employed for its determination in U3O8. The method gives a precision and accuracy of 4.0% at 100 ppb of boron when about 200 mg sample is taken for analysis; the detection limit is 32 ng of boron. If the availability of the sample is limited and the boron content is low, lower dilutions are resorted to realize the desired sensitivity in the measurements (diluting to 10 mL instead of 25 mL). Interference of different acid media is also discussed.
