Spectrophotometric Determination of Cr_2O_7~(2-)with 2-(3,5-dibromo-2-pyridy lazo)-5-dieth-Laminophenol and SCN~-

Li Xin(Department of chermistry,Gansu Educational college,Lanzhou,730000)  
This paper investigates the optimum reaction conditions among 2-(3,5-dibromo-2-pyridylazo)-5-diethylaminophenol (3,5-dibromo-PADAP),Cr2O72-and SCN-in H2SO4 medium.The molar absorptivity of the reaction product is 1.44×105L·mol·cm-1.A new method for-the determination of microamount of Cr2O72-has been there by established and applied to determine microamount of chromium (v1) in a drinking water and a sample of iron steel with satisfactory results.
