| Abstract: | The Spectrophotometric properties of Molybdenum(VI)-SCN-CV-TBF-Emulsifying Agent OP ligand System were studied .The system has its absorption maximun at 578 nm wit the range of in 0.10～0.25 mol/L sulfuric acid sdution .The apparent molar absorptrivity is 2.9×10 6L/(mol·cm) at λ max =578nm,and the blank correction at 578nm approaches to zero .composition ratio is Mo(VI)∶SCN∶CV-TBF=1∶6∶3.Beer′s law is obeyed in the range of 0 to 4.0 μg Mo 6+ /50ml.This method proves to be satisfactory for the direct Determination of Trace Mo in Serum and Human Hair .The recoveris were 98%～103%.This method have not been reported up till now. |
