| Abstract: | A method was introduced to determine trace vanadium(Ⅴ) in environmental samples by oxidation of Rhodamine B with potassium periodate in the medium of phosphoric acid,with maximum absorption of wave length 530nm, apparent molar absorption 2.71×10~8L. mol~(-1). cm~(-1), which were in consistence with Beer's Law in range of 0～30ng/25mL The method was used to determine trace vanadium in drinking water and wheat with satisfactory results. |
