近年来锰砂作为一种新兴的去除水中铁、锰离子的滤料,被广泛应用于地下水除铁、除锰技术中。锰砂中的二氧化锰是去除水中铁、锰的主要有用成分。因而监控分析锰砂中二氧化锰很有必要。但目前对于锰砂中二氧化锰质量分数的测定没有统一的标准。笔者在实践中总结出用过硫酸铵分光光度法测定锰砂中的二氧化锰。此法操作简便易行,现将该法介绍如下。1方法原理
In recent years, manganese sand as a new removal of iron and manganese ions in the water filter, is widely used in groundwater removal of iron, manganese removal technology. Manganese dioxide in manganese sand is the main useful component to remove iron and manganese in water. Therefore, it is necessary to monitor and analyze the manganese dioxide in manganese sand. However, there is no uniform standard for the determination of the mass fraction of manganese dioxide in manganese sand. In practice, the author summarizes the use of ammonium sulfate spectrophotometry manganese dioxide in the manganese dioxide. This method is easy to operate, now the law is as follows. 1 method principle
