电镀车间空气中Cr(Ⅵ)的在线检测方法和装置

On-line Determination Method and Device of Cr(V) in Air of Planting Workshop

利用铬 (Ⅵ )可以和二苯基碳酰二肼 (DPC)形成紫红色的螯合物 ,设计了一套流动注射—分光光度在线监测装置测量电镀车间空气中的铬 (Ⅵ )。该装置原理简单 ,设备容易实现 ,操作易掌握 。

As an important environmental contaminant, Cr(Ⅴ) do harmful to health. Many methods for the determination of Cr(Ⅴ) were reported expect the on line detection method of Cr(Ⅴ) in planting workshop air. Base on the reaction of Cr(Ⅴ) and DPC(diphenyl carbazide) ,an on line detection device of flow injection spectrophotometric method was designed for the detection of Cr(Ⅴ) in air of planting workshop.
