The present invention relates to a hydroxyapatite-zeolite composite in which a phosphoric acid solution, cetyltrimethylammonium bromide (CTAB), and an alkali activator are mixed with industrial by-products such as fly ash and fine slag powder and hydroxyapatite capable of adsorbing anions and zeolite capable of adsorbing cations are simultaneously synthesized so that large amounts of cations and anions can be absorbed. 본 발명은 플라이애쉬와 슬래그 미분말과 같은 산업부산물에 인산 용액과 브롬화세틸트리메틸암모늄(CTAB; Cetyl trimethylammonium bromide) 및 알칼리 활성화제 등을 혼합하여 음이온 흡착에 능한 수산화인회석과 양이온 흡착에 능한 제올라이트를 동시에 합성함으로써 양이온과 음이온을 대량으로 흡착할 수 있는 수산화인회석-제올라이트 복합체 및 그 제조 방법에 관한 것이다.
