Abstract

In this study, a new organophosphorus acid-based solvent (KMC-P) from KMC Co., Ltd. was used for the recovery of the iron chloride etching waste solution. In order to increase the extraction efficiency for the new solvent in the solvent extraction process, we selected the process variables and conducted the optimization experiment according to the DOE to investigate the correlation between the variables. Solvent concentration, pH, and O/A ratio were found to be factors affecting extraction and stripping efficiency. The optimum stripping efficiency was 69.7% when the solvent concentration was 29.4 wt%, the HCl addition amount was 0 mL, and the O/A ratio was 7, and the reliability was more than 86%.

본 연구에서는 염화철 에칭폐액 재생을 위하여 (주)케이엠씨에서 조합한 organophosphorus acid계의 신규용매(KMC-P)를 사용하였으며, 용매추출공정에서 신규 용매에 대한 추출효율을 증가시키기 위해 공정변수를 선정하고 변수간의 상관관계를 알아보기 위해서 DOE에 따른 최적화실험을 진행하였다. 용매 농도, pH, O/A ratio가 추출, 탈거효율에 영향을 미치는 인자로 나타났으며 최적의 탈거효율을 갖는 공정조건은 용매 농도 29.4 wt%, HCl 첨가량 0 mL, O/A ratio 7일 때, 최대 69.7%의 탈거효율을 기대할 수 있는 결과를 얻었으며 신뢰 수준은 86% 이상인 것을 확인하였다.
