水质简易测定器

VISOCOLOR ECO 碳酸盐硬度

作者：admin 添加时间：2017-02-04 16:27:30 浏览：

大发平台网站 www.tjyhzw.com VISOCOLOR^? ECO碳酸盐硬度

滴定法测试碳酸盐硬度

测定的方法是用盐酸滴定混合指示剂，在PH值为4.5。（反应的基础上，根据DIN EN ISO 9963-1 C24）

编号	931 014
类型	滴定测试
测试范围	1 滴 = 1 °d
测试次数	100 次（平均硬度为10 °d的情况下）
保质期	2 年
海水分析	适用
使用PF-12测试	不适用

碳酸盐硬度是一部分钙和镁离子，这是目前作为碳酸酯或碳酸氢。

通常情况下，碳酸盐硬度小于总硬度。如果碳酸盐硬度大于总硬度，则应追溯这种异常情况的来源，例如：碱氢碳酸盐岩的排放或高缓冲容量。
