近年来络合滴定法找到了性能更好的隐蔽剂,使络合滴定法的使用范围更为广阔了。但是以手工操作的络合滴定法之分析时间较长,为了使络合滴定法也能达到高速分析,我厂设计制造了一套络合滴定的机械化设备(图1)。用此设备进行络合滴定法可以大大缩短分析时间。以分析青铜中四种元素(铜、铅、锌、锡)为例,手工操作时,两位化验人员用20～25 In recent years, complexometric titration has found a better performance of concealment agent, the use of complexometric titration is more broad. However, the manual analysis of the complexation titration longer, in order to make the complexation titration can achieve high-speed analysis, I designed and manufactured a set of complexation titration mechanized equipment (Figure 1). Complex titration with this device can greatly reduce the analysis time. To analyze the four elements of bronze (copper, lead, zinc, tin), for example, the manual operation, two laboratory staff with 20 ~ 25
