Abstract

본 발명은 불소(下)가 함유된 폐수에서 용존불소 이온을 선택적이며 효과적으로 제거하기 위해 가용성 회토류 화합물을 이용하여 불소를 처리시 이에 사용되는 가용성 회토류 화합물의 조성에 관한 것으로, 불소함유 폐수를 가용성 회토류 화합물로 처리하는 처리제에 있어서, 회토류 성분 중 세륨(Ce)성분이 10중량% 미만임을 특징으로 하는 불소함유 폐수 처리제에 관한 기술이다.The present invention relates to the composition of soluble rare earth compounds used in treating fluorine using soluble rare earth compounds in order to selectively and effectively remove dissolved fluorine ions from wastewater containing fluorine. A treatment agent for treating with a soluble rare earth compound, wherein the cerium (Ce) component in the rare earth component is less than 10% by weight.
