Abstract
본 발명은 산화제일구리(Cu2O)의 제조방법에 관한 것으로서, 더욱 상세하게는 전자산업에서 중금속 폐기물로 대량 배출되고 있는 구리성분이 함유된 산폐액을 강알카리로 중화시킨 후, 아황산나트륨(Na2SO3)을 이용하여 환원시키므로써 유리 또는 에나멜 등의 안료 또는 도료의 원료로서, 살균제 또는 어망 등의 착색제, 방부제 또는 선박의 오염방지 페인트 원료로서, 그리고 촉매 등으로 유용한 오렌지색 산화제일구리의 제조방법에 관한 것이다.The present invention relates to a method for producing cuprous oxide (Cu 2 O), and more particularly, after neutralizing the acid waste liquid containing a copper component that is largely discharged as heavy metal waste in the electronics industry with strong alkali, sodium sulfite ( Na 2 SO 3 ) is used as a raw material of pigments or paints, such as glass or enamel, colorants such as disinfectants or fishing nets, preservatives or raw materials of anti-fouling paint of ships, and useful as catalysts. It relates to a manufacturing method.
