초록

본 연구에서는 해수로부터 마그네슘을 농축하기 위하여 세 가지 침전제(NaOH, 시멘트 킬른 더스트, 제지슬러지소각재)를 이용하여 마그네슘을 침전시키고, 황산을 이용하여 마그네슘을 용출하는 실험을 진행하였다. 사용한 침전제의 종류와 상관없이 침전반응 효율은 거의 100%이었고, 용출반응 효율은 77 - 89%로 비슷하였다. 용출액의 마그네슘 농도가 4975 - 5775 mg/L이었는데, 이것은 침전반응과 용출반응을 통해 해수의 마그네슘이 3.8 - 4.4배 농축되었음을 의미한다. 본 연구에서 침전제로 사용한 산업부산물의 반응효율은 거의 100%로 기존의 고가 침전제와 비슷하였다.

With the purpose of concentrating the magnesium from seawater, in this study, we have conducted experiments to precipitate the magnesium using three precipitants (NaOH, cement kiln dust, and paper sludge ash), and then extract it using sulfuric acid. Results show that the precipitation and extraction performance does not depend so significantly on the kind of precipitant: for all the precipitants used, the precipitation efficiency is measured almost 100% and the extraction efficiency is in the short range of 77 - 89%. The magnesium concentration in the extract is measured 4975 - 5775 mg/L, implying that the magnesium in seawater should be 3.8 - 4.4 times concentrated through the precipitation and extraction reactions. The reaction efficiency of the industrial by-product used as a precipitant in this study is almost 100% similar to those of the other existing expensive precipitants.
