| Abstract: | It has been found that a sensitive polarographic catalytic wave of vanadium is produced in the system of 3,5-Cl_2-DMPAP-NaBrO_3.The wave height is propor- tional to the concentration vanadium in the range 0,04-12ppb.The method has been developed for the determination of trace amounts of vanadium in water and human hair with good results. |
