시안의 사용처는 무엇인가? | 시안(cyanide)는 도금, 의학, 채광 및 자동차 산업에서 광범위하게 사용되고 있으며, 또한 이들 공정에서 많이 발생되고 있다(Mudliar et al., 2009; Zagury et al. | |
시안 이온의 특징은 무엇인가? | , 2004). 시안 이온(free cyanide)은 자체로 매우 유독할 뿐 아니라 카드뮴(Cd), 구리(Cu), 니켈(Ni) 등의 전이금속(transition metal) 등과 강한 복합체를 형성하며, 이러한 시안화합물은 생물체에 악영향을 주는 것으로 알려져 있다. 따라서 시안이 함유된 폐수의 처리는 도금 공업 등에서 가장 중요한 현안으로 인식되어 왔다(Choi and Park, 1997; Kim et al. | |
시안화합물 완전분해의 한계르 극복하기 위한 방법은 무엇인가? | 시안이온과는 달리 전이금속과 강력한 복합체를 형성하고 있는 시안화합물 등은 위에서 언급한 처리공정으로그 완전분해의 한계를 가지고 있다. 따라서, 이러한 문제점을 극복하기 위한 방법으로는 산화제를 투입한 물리-화학적 공정(Haag and Yao, 1992), 오존(ozone) 산화법(Gurol and Holden, 1988; Zeevalkink et al., 1980), 광촉매(photocatalysis)인 titanium dioxide (TiO2)를 이용한 처리공정(Pedraza-Avella et al., 2008), ferrate (VI) 산화공정(Yngard et al., 2008) 등이 연구되고 있다. |
