The digested water samples were analyzed for the presence of Copper, Zinc and Lead using the scientific Nov 300 Atomic Absorption Spectrophotometer.
The calibration plot method was used for analysis. The air acetylene was the flame used and hallow
cathode lamp of the corresponding element was the resonance. Line source, the wave length for the determination of three elements were 283.31, 324.7 and 213.9 nm for Lead, Copper and Zinc respectively.
