摘要
提出一种基于化学计量学方法的水硬度的测量方法。以分光光度法为基础,结合传统的乙二胺四乙酸(EDTA)络合滴定法和现代光电子技术,力求实现水硬度测量的简便和快速。采用单片机控制,以三个特定波长的单色光实现非连续光谱分析,从而实现仪器的小型化和便携性。
?A measurement method of water hardness based on chemometrics is presented.Compared with traditional EDTA method,this method applies spectrophotometry combined with modern photoelectron technology.Three specified wavelength monochrome instead of continuous spectrum is applied so that it is possible to make the equipment portable.At the same time,single chip processor is introduced so as to make it convenient to handle.
