Abstract
In this study, the metallic element Nickel has been determined in water samples from selected stations along the southern part of Shatt Al-Arab river which extended from: 1) Garmat Ali, 2) Mhelah in Abu Al-Khaseeb, 3) the discharging point of Karon river in Shatt Al-Arab River, 4) Al-Seebah in front of Abadan refinery and 5) Al-Fao, the point between Al-Nagha'ah and the Costumer Station. A spectroscopic method was adopted for determination of nickel after the formation of complex between nickel ion and porpharine compound which already prepared from the reaction between pyrrole and benzaldehyde (0.8 moles each) by soxhlet in prop ionic acid for 30 minutes. Measurements were performed at wave length 515 nm. For comparison and accuracy detection of this method another measurements were done by Atomic Absorption Technique. Values recorded spectrophotometerically for nickel were: 0.0860, 0.064, 0.063, 0.107 and 0.0865 mg/l for the stations 1-5 respectively compared with values 0.0865, 0.065, 0.065, 0.1085 and 0.0868 mg/l for the same stations respectively. As it is expected, the highest level of nickel was recorded in station 4 which is affected by discharging effluent from Abadan refinery. The study revealed that this complex is suitable for the determination of Nickel in water samples.
