- W2372398839 abstract "Chromium (Ⅵ) in water was detected by the UV spectrophotometric method which based on the color reaction of Cr (Ⅵ) with diphenylcarbazide hydrazine to form purple complexes in acidic conditions. The optimized conditions were also studied. The maximum absorption wavelength at 540 nm and the linear range in 5.2×10-3 mg·L-1～1.2×10-1 mg·L-1 which was in accordance with the Beer's law were observed. The results showed that the UV spectrophotometric method was sensitive , simplified and specific and suit for determination of Cr(VI) in natural and waste water." @default.
