The present study was conducted on Najibia and Hartha power plants to assess the physico-chemical characteristics of power plant effluents and to investigate the environmental impact resulting from them. The water samples from both power plants were collected for four weeks during Summer season in 2012 where water samples were taken from three sites (Inlet water, outlet cooling and outlet Industrial water) for analyzing seven parameters (water temperature, pH, electrical conductivity, total suspended solids, chloride, total phosphorus and total iron). Water temperature increased at site 2 (outlet cooling water) comparable with site 1 (inlet water) at Najibia and Hartha power plants, at Najibia power plant it exceeded Iraqi guideline value of waste effluents (˂ 35 ◦C) while at Hartha one it was within that guideline. pH values of the sampling sites at both power plants were found to be neutral to alkaline in nature, pH value of site 1 was within the Iraqi guideline value of surface water (6.5-8.5) and the effluents of both site 2 (outlet cooling water) and 3 (outlet industrial water) were within the Iraqi guideline value (6-9.5) of waste effluents which had no effect upon aquatic organisms. Electrical conductivity elevated at site 2 at Najibia power plant due to high temperature while at Hartha power plant, water electrical conductivity of site 2 was lower than that of site 1, the electrical conductivity result of site 3 at Najibia power plant was higher than that of site 1, and at Hartha power plant it was lower than that of site 1. The highest average of suspended solids was at site 3 in Najibia power plant comparable with other sites while at Hartha power plant the least average of suspended solids was at site 3 comparable with the other sites. However, the effluents of both site 2 and 3 at both power plants did not exceed Iraqi guideline value (60 mg / l) of waste effluents. The average values of chloride ion for site 1 and 2 at both power plants were less than 1000 mg/l and this indicated that river water was suitable for cooling purpose while the average chloride's ion values of site 3 at both power plants were within the Iraqi guideline value (600 mg/l) of waste effluents where they did not threaten the life of aquatic organisms. The prevalence of phosphorus compounds in industrial wastes referred to water treatment processes and the results of all sampling sites at both power plants were very high to produce eutrophiction phenomenon where it occurs in an aquatic environment when concentration of orthophosphorus is only 0.005 to 0.05 mg/l .The average values of total iron at site 1 did not exceed the guideline value (1 mg/l) of U.S. Environmental Protection Agency (1986) for freshwater aquatic life. Where as the concentrations of total iron in site 2 and site 3 at both power plants were within the Iraqi guideline value of waste effluents (2 mg/l).

The distribution and possible sources of 16 polycyclic aromatic hydrocarbons (PAHs) were investigated in the surface sediments of Diwaniah and Daghara rivers in AL- Qadissiah province in Iraq during the period from March 2011 to February 2012, surface sediment samples were collected from four locations in Diwaniah, and Daghara river sited along rivers and other station on Hilla river which were branched from it. Sixteen PAHs were identified and quantified in sediments sample by High performance liquid chromatography (HPLC). Concentration of total PAHs ranged between (2.19--354.55ng/g dry weight)were recorded at St.1 on Hilla river during Aug. and St.5 on Diwaniah river through Mar. respectively. with annual mean concentrations of ΣPAH ranged between (37.4--90.7 ng/g) at Hilla river and St5 on Diwaniyah respectively. The maximum concentration of individual PAH were detected of Pyrene (96.9ng/g)at St.2 on Daghara river while some high molecular weight HMW such BaP ,IND and BkF no detected during some months . Compositional pattern analysis investigated that 2-3ring of individual PAHs was highest ratio in comparing with 4,5.6 ring whereas 6ring was lowest ratio in all stations. Diwaniah and Daghara rivers were moderately polluted by PAHs (∑16PAH=250-500ng/g) while Hilla river was slightly polluted (∑16PAH <250ng/g).
Diagnostic ratios suggested that possible source of PAHs were mixed sources among pyrogenic and petrogenic origin in the study region.
The results of current study showed that total organic carbon (TOC)in sediment sample ranged between (0.2-3.2%) at Hilla and Diwaniah rivers also respectively, Grain size distribution test illustrated that sandy nature was abundant in all stations. PAHs do not correlate with the particle size distributions but it significant correlated with the content of the TOC in sediment.

journal of al-qadisiyah for pure science(quarterly), Volume 14, Issue 1, Pages 1-15

The photo degradation of Azure A (AA) dye by using ozone as a stimulating agent with ultra violet radiation (O3/UV) has been studied. All dye solutions has been subjected to color removal. The study includes the effect of the concentration of dye solution, temperature, pH, air flow rate, and the light intensity on the degree of color removal. It was found that the increase in dye concentration leads to adecrease in removal rate. Also, the rate of dye removal increases with the increase in temperature. The activation energy reached (13.06 kJ/mole). Concerning pH is the removal decreases in acidic medium because the ozone doesn’t decompose to hydroxyl radicals. Contrastively, the rate of removal increases in basic medium because of the decrease of solubility of ozone and the formation of hydroxyl radicals. Another important result is that the rate of air is associated positively with the rate of dye removal. Lastly, it is noticed that the more light intensity increased, the more the rate of color removal increased. Generally , The ratio of the chemical oxygen demand (COD) increases with the increase of color removal. The maximum ratio of color and COD removal, that was reached (at 45 oC ), was 98.1% and 68% respectively.

A simple,Sensitive spectrophotomettric method was proposed for the micro determination of Cu(ᴨ) using the synthesized P-bis (4-chloro phenyl-imine) phenylenes (p-b(cpi)p). The method was based on the formation of (1:3) complex between the Cu(Π) and the ligand. The optimum conditions for the determination were established, The beer's law Was applicable in the rang (1-25)μg/ml. The complex has maximum absorption at 470 nm and molar absorption coefficient and stability constant of the complex was found to be ( 7.7×103 )L.molˉ¹.cm‾¹(4.8×107) respectively .The limits of detection and quantitation for the developed method are (1.12 ×10-2 )and (3.38 ×10-2 )µg ml-1respectively. The method was simple, sensitive, accurate and was successfully applied for the determination of copper (II).

This study involved preparation of new ligand as( ammonium( 4-amino antipyriyl -N-dithiocarbamate) (APDTC) was prepared by reacting of (1-phenyl-2,3-dimethyl-4-amino antipyrine) with carbon disulfide (CS2) in the presence of ammonium hydroxide .With this ligand, three metal complexes of Cu(II),Co(II) and Fe (III) were also synthesized under the established optimum conditions. A number of experimental techniques (such as IR, UV-Vis spectrophotometry, conductometry etc) were used to determine a crucial characterization and determination of the structures of these compounds. The data shows that the both complexes combin in molar ratio(metal ion to ligand) of 1:2 and the stability of the complexes were studies.The conductivity and magnetic susceptibility data reveals that the both complexes were non-ionic in DMSO and paramagnetic in their nature the chemical structures of the Fe (III) and Cu (II)complexes were also suggested.
