Removal of Nickel from the Etching Waste Solution of Ferric Chloride

초록

엣칭용 염화제2철 용액중의 효과적인 니켈제거에 관해 연구하였다. 전해철괴 또는 폐새도우마스크 철편을 사용하여 염화제2철을 염화제1철로 환원시킨후 용액중의 Ni₂₊를 전해철 분말로 환원 석출시켰다. 최적의 실험조건하에서 초기 니켈의 농도가 1.0%일 때 니켈제거율은 99%이었고 초기 니켈의 농도가 0.1%일 때 니켈제거율은 98%이었다. 염화제2철의 환원반응 중에 생성된 수산화철의 종류 및 입자크기를 XRD와 SEM으로 분석하였다.

Efficient removal of nickel from the ferric chloride etching solution has been studied. At first, Fe³⁺was reduced to Fe²⁺by the electrolytic iron flake or the waste shadow mask iron plate. And then, Ni²⁺was removed from the solution by electrolytic iron powder. Under the optimum conditions the reduced rates of nickel were 99 % and 98%, respectively at the initial Ni²⁺concentrations of 1.0% and 0.1%. Sludge formed during reduction of Fe³⁺ in the solution were analyzed by XRD and SEM.
