dc.description.abstractA simple and low cost method been utilized for the tenaciousness of trace copper ions in dental – unit wastewater samples. The method is predicated on the reaction of copper ions with the reagent 4-(3,5-dibromo-2- pyridylazo)-N-Ethyl-N-(3-sulphopropyl) aniline (3,5-di-Br-PAESA) in acidic medium .The composed intricate shows an absorption maximum at 580nm at max was obtained employing acidic buffer for intricate reaction to take place. Plots of the colored Cu –reagent intricate were obeyed in the concentration range 6.25-50ug/ml-1copper ions, respectively with a relative standard deviation in the range of 2±1 %. The inhibition of the detection (LOD) and quantitation (LOQ) of the procedure were 0.02 and 0.1ng/ml-1 Cu2+respectively. The proposed method was applied for the analysis of copper in dental-unit wastewater samples.
