用氫氧化銨及氯化銨以分離銅與鐵,結果很好.氫氧化鐵中所留銅量,在實用分析上,已少至毋須考慮.用此法自多量鐵中分離少量銅份,可直接用此色法测定.五價砷與銻存在時,如不超過10毫克,或磷酸根不超過50毫克時,不影響銅與鐵的分離.鋁對分離更無影響.

The extent of copracipitation of copper with ferric hydroxide in the ammonium chloride-ammonia process has been studied. Pentavalent araenic and antimony may be present up to 10 mg, and phosphate, 50 mg. Aluminum exerts little effect. It is found that this mothod yields satisfactory results. The amount of copper coprecipitated in the ferric hydroxide precipitate is negligible in practical analysis.
