Abstract

In this research, in order to effectively utilize the petroleum residue pitch, it was used as an adsorbent for removal of cesium ion. In this experiment, acid modification (hydrochloric acid, sulfuric acid) treatment was performed on the adsorbent to improve the ability to remove low-concentration cesium ions dissolved in water. As a result, when the reaction was performed with 9 M sulfuric acid at 25 ℃ and for 240 min, the removal efficiencies of 1.0 and 2.5 mg/L cesium ions were 66 and 51%, respectively. In addition, as the adsorption time increased in the batch experiment, the removal capacity of 1.0 and 2.5 mg/L cesium ions was improved, and when the adsorption reached for 32 hr, the removal efficiencies were 72 and 68%, respectively. Also, in order to increase the ability to remove the remaining cesium ions, an experiment was performed by temperature change (25, 37, 49 ℃), and 1.0 and 2.5 mg/L cesium ions contained in water under the operating conditions of 49 ℃ and 32 hr showed removal efficiencies of 90 and 81%, respectively. Consequently, these experimental results were intended to be used as an adsorption technology that can economically treat low-concentration cesium ions contained in water.

본 연구에서는 석유계 잔사유 피치를 효과적으로 활용하고자, 세슘 이온의 제거를 위한 흡착제로 사용하였다. 이 실험에서는 수중에 용해된 저농도 세슘 이온의 제거능력 향상을 위하여 흡착제에 산 개질(염산, 황산)처리가 수행되었다. 그 결과, 9 M 황산으로 개질된 흡착제가 25 ℃에서 240 min 반응이 이루어졌을 때, 1.0과 2.5 mg/L의 세슘 이온의 제거효율은 각각 66, 51%를 나타내었다. 또한, 회분식 공정에서 흡착 시간이 증가할수록 1.0과 2.5 mg/L의 세슘 이온 제거능력이 향상되었으며, 32 hr 흡착에 도달하였을 때 각각 72, 68%의 제거효율을 나타내었다. 그리고 잔존하는 세슘 이온의 제거 능력을 높이고자, 온도 변화(25, 37, 49 ℃)에 의한 실험이 이루어졌으며, 49 ℃와 32 hr의 운전 조건에서 수중에 함유된 1.0과 2.5 mg/L 세슘이온은 각각 90, 81%의 제거효율을 얻을 수 있었다. 따라서 이러한 실험 결과들은 수중에 함유된 저농도 세슘 이온을 경제적으로 처리할 수 있는 흡착 기술로 사용하고자 하였다.
