الملخص EN
Flow-through stripping chronopotentiometry with a gold wire electrode was used for the determination of total arsenic and cadmium in cadmium sulphate solutions for cadmium production.
The analysis is based on the online separation of arsenic as arsenate anion from cadmium cations by means of a cation exchanger.
On measuring arsenate in the effluent, the trapped cadmium is eluted by sodium chloride solution and determined in a small segment of the effluent by making use of the same electrode.
The elaborated protocol enables a full automatic measurement of both species in the same sample solution.
The accuracy of the results was confirmed by atomic absorption spectrometry.
The LOD and LOQ for Arsenic were found to be 0.9 μg dm-3 and 2.7 μg dm-3, respectively.
A linear response range was observed in the concentration range of 1 to 300 μg dm-3 for sample volumes of 4 mL.
The repeatability and reproducibility were found to be 2.9% and 5.2%, respectively.
The linear response range for cadmium was found to be 0.5 to 60 g/L.
The method was tested on samples from a cadmium production plant.
