The present study was undertaken to investigate a method for boron removal from wastewaters from boric acid and borax plants. The ion-exchange method is effective for the removal of boron from solution. The experimental results under different initial concentrations are first converted into dimensionless variables by taking ratios of volumes and concentrations and subsequently plotted on double logarithmic graph papers. The scatter diagram appeared as a straight line on double logarithmic paper, which implied an empirical relationship as C/C-0 = 0.05 (V-1/V-2)(2.72) where C and C-0 are the effluent boron concentrations at any time and initial time, respectively. In short, there appears to be a power relationship between the dimensionless concentrations and volume variables.
