摘要
以国家标准方法为基础,对铁矿石样品采用不同的溶剂来溶解样品,在对其含锌量分别进行测试,文章采用国标(萃取)和加氨水的方法,分别进行试验,两种方法对比,不仅简化了操作流程,而且误差小,具有较高的准确性和可靠性。
Based on the national standard method,the iron ore sample is dissolved by different solvents,the zinc content is tested separately,the article uses the national standard (extraction) and ammonia method,the two methods are compared,not only simplifies the operation process,but also has a small error,with high accuracy and reliability.
