Determination of Boron in Water Samples by the Spectrophotometric Curcumin Method

Abstract:

The boron concentrations in water samples from the Yellow River and a reservoir were measured by the spectrophotometric curcumin method. Results show that there is a good linear relationship between the absorbance and the concentration (R2=0.9991). The sensitivity of this method was 0.029 µg, and the precision is 2.05%~5.41%. For different treatments of solutions, the recovery of added boron was in the range of 96.3 to 106.2%. This method is sensitive, accurate, reproducible and easy to be operated.
