随着分析化学的不断发展和进步,对矿石铜量的测定与改进成了一些研究员的新型课题。以往来看,碘量法是测定铜的经典方法,在冶金领域应用极为广泛,在碘量法中,乙酸—乙酸铵缓冲液运用较多,然而通过实验对比发现,用乙酸—乙酸钠代替乙酸—乙酸铵是可以投入正常生产过程的,而且相比较而言,由于乙酸钠属于有毒化学物品,在长期存放时对安全管理要求过高,所以乙酸—乙酸钠的利用对环境的保护和安全的处理占据优势。所以本文将以实验为载体,具体介绍乙酸—乙酸钠的生产作用,以及对碘量法的实际改进。
With the continuous development and progress of analytical chemistry, the determination and improvement of the amount of copper in the ore has become a new topic for some researchers. In the past, the iodometric method is a classic method for the determination of copper and is widely used in the field of metallurgy. In the iodometric method, acetate-ammonium acetate buffer is used more, however, it is found by experiment that acetic acid-sodium acetate is used instead of acetic acid - Ammonium acetate can be put into normal production process, and in comparison, since sodium acetate is a toxic chemical and requires too much safety management in long-term storage, the use of acetic acid-sodium acetate is environmentally safe and safe Processing dominated. Therefore, this article will be experimental as a carrier, a specific introduction acetic acid - sodium acetate production, as well as the actual improvement of iodometric method.
