초록

본 연구에서는 염수 중 보론의 최적 용매추출 조건 도출을 목적으로 diol계 TMPD(2,2,4-trimethyl-1,3-pentanediol)에 의한 보론 추출거동을 조사하였다. 0.736 g/L의 보론을 함유하고 있는 염수 용액을 시료로 하여 추출실험한 결과, 추출제 농도 0.75 mol/L, 두 상간의 부피비 1, 염수의 pH 3, 교반시간 20분, 추출온도 298 K에서 99% 이상의 추출율을 나타내었으며, 탈거반응의 경우, 수산화나트륨 농도 1 mol/L에서 99% 이상의 탈거율을 나타냄으로써 염수 중 잔존 보론 농도를 10 ppm 이하로 제어 가능하였다. 또한 실험 결과로부터 pH 6 이하에서 다음과 같은 추출평형 반응식을 도출할 수 있었다. log D = 1.7 log $[TMPD]_O$ + constant at pH < 6.

A study on the behavior of boron extraction by TMPD(2,2,4-trimethyl-1,3-pentanediol) was carried out to find the optimum conditions for the boron extraction from brine. In case of boron extraction from 0.736 g/L boron-containing brine, typical optimum extractive conditions would be confirmed to be 0.75 mol/L of extractant concentration at 3.0 pH of brine with 1 of phase ratio and 20 min. of shaking time at 298 K respectively. And 1 mol/L sodium hydroxide of stripping agent was shown above 99 % of boron extraction and stripping efficiencies. Also, extraction equilibrium equation were obtained through experiments as follows : log D = 1.7 log $[TMPD]_O$ + constant at pH < 6.
