| Descripción: | Direct determination of copper at the presence of Pb2+, Cd2+, Sn2+, Sn4+, Co2+, Ni2+, Fe2+, Fe3+, Cr3+, Cr6+, Zn2+, Mn2+, As 3+, As 5+, ions was carried out using thiosemicarbazide as complexing agent by UV-VIS spectrophotometry. The peak of Cu 2+-thiosemicarbazide complex at 356 nm in 0.1 M HNO3 (aq) was taken to be reference. With the application of same method to the top water, the amount of Cu 2+, in tap water was determined to be 0.11±0,03 mg/L. This method is important as it requires no pre-seperation technique and it is sensitive upto 1.0x10-6 M. Key Words: Direct determination, Copper, UV-VIS spectrophotometry, Thiosemicarbazide. |
