| Abstract: | In this papet,a self-made device for continuous monitoring of elution process in extraction chromatography with post-column spectrophotometry is described. It consists of(a) a valve for gradient elution,made of nylon,(b)a six-way sample iulet valve,made of polytetrafluoroethylene (PTFE),(c) a fout-way mixing chamber,(d)a coiled tube reactor,and(e) a flow-through cuvette, made of PTFE. An atomic absorption spectrometer (Model WFD-Y3,Beijing 2nd Optical Instruments Corp) was converted into a flow-through photometer by taking out the original burner and put the flow-through cuvette in its place. A hollow cathode lamp served as light source.The pats described were assembled together as shown in Fig,1 in the Chinese version.It has been used to separate fifteen rare earths with satisfactory results. |
