MATHEMATICAL-MODEL FOR ADSORPTION OF BORIC-ACID ON A BORON-SPECIFIC ION-EXCHANGER

The present study was undertaken to investigate boron removal from the waste waters of borax and boric acid producing plants. A boron-specif ic resin, Amberlite XE 243, was selected for the present work. Experim ental results show that the ion-exchange operations are effective in r emoving boron from the waste waters. The variation of boron concentrat ions in the effluents has been observed to depend, for various initial boron concentrations, C-0, on the ratio of the filtrate volume to the volume occupied by resin. An empirical equation has been developed re lating boron concentration, C, to filtrate and resin volumes V-1 and V , respectively, as C = 2.34 x 10(-6). C-0(V)(-0.043)(V-1)(2.80)
