| Abstract: | The spectrophotometric determination of zinc in waste water has been studied. The resulting complex has a maximum absorption at 213- 9 nm Beer's law was obeyed in the concentration range of 0. 022-1. 250 mg/L, and the correlation coefficient was 0. 9991. The method was applied to determine Zinc in waste water with satisfactory results. The relative standard deviations were less than 5%. and the recovery of zinc ranged from 98% ~105% of added amount. |
