| 摘 要： | 提出了一种基于图像识别技术的水中总碱度的自动测量方法及装置.以盐酸为滴定剂,溴甲酚绿为指示剂,根据酸碱中和原理,利用等当点时溶液R、G、B值的突跃确定滴定终点,从而测出水中总碱度.实验结果表明,该方法测量碱度的线性范围为0.2～40 mmoL/L,相对标准偏差为0.43％,加标回收率为96.4％～102.6％.用于工业循环冷却水中总碱度的测定,具有操作简便、准确度高的特点,可实现碱度的自动测量.

| Abstract: | A new automatic measuring method and device of alkalinity in water based on image identification technology are proposed in this paper.Based on the principles of acid-base titration,hydrochloric acid is used as the titrant and bromcresol green as the indicator,the equivalent point of titration is identified by a RGB-based value that is calculated using a proposed procedure based on red,green and blue color system;and the total alkalinity of the water can be measured.Experimental results show that the linear... |
