摘要
用EDTA滴定法对三个生活饮用水样品总硬度进行了检测,采用改良后的固体指示剂来判断滴定终点,结果表明该方法方便、快速,结果准确可靠。影响水总硬度测定的因素主要有:水样p H值、滴定的温度、缓冲溶液、指示剂、滴定时间及滴定速度等。
In the research,we detect three drinking water samples for total hardness with EDTA titration method,including using modified solid indicator to judge the titration end point. As a result the method is convenient,rapid,accurate and reliable. The impact factors of the detection of water total hardness mainly include： the samples p H value,the titration temperature,buffer solution,indicator,titration time and titration rate,etc.
