摘要
研究了酸性溶液中高锰酸与罗丹明Ｂ的褪色反应，确定了最佳测定条件，方法具有较好的选择性。锰量在０３５３０μｇ／５０ｍＬ符合比耳定律。用于粘土、灰岩物质及水样中锰的测定，结果满意。
The oxidation color fading reaction of permanganate with Rhodamine B in a medium was studied. The optimal reaction conditions were determinated. The selectivity of this method is very good. The Beer′s law is obeyed from 0￣30 μg Mn(Ⅱ) in 50 ml. This method was applied to the determination of Manganese in clay, marl and water, good results were obtained.
