Determination of Lead Levels in Fuel Used for Vehicles in Baghdad City
...Show More Authors

     The wide use of lead compounds as an engine anti-knock reflects conversely on all components of the ecosystem. This study aimed to detect the concentration of lead in various types of gasoline and gas oil that are highly consumed by vehicles. Eight fuel samples were collected from different feul stations distributed in different districts of Baghdad city. These included two gas oil (diesel) stations and three stations for each type of gasoline (leaded and unleaded). Lead was extracted by the modified chemical method, and then flame atomic absorption technique was applied to assay its concentrations. The results indicated that lead levels were within permitted limits (150 mg Lead L-1) recommended by the international agencies. The highest lead mean concentration was 105 mg/L, recorded in Latifiya leaded gasoline, whereas the lowest mean was 3.1mg/L in unleaded gasoline imported from the United Arab Emirate. As for gas oil, lead concentration occurred within a mean of 1.85-2.05 mg/L. The influence of some leaded gasoline improvements, octane booster and octane plus, was estimated, which revealed sharp declines in lead mean concentrationsto values of 1.05 and 5.2 mg/L for Latifiya and Rusafa gasoline, respectively. Furthermore, the daily lead emission was estimated for the registered vehicles in Baghdad and revealed a high concentration of 1837.7 µg lead m-3 for private cars. This study proposes avoiding the addition of lead compounds to fuel, in order to reduce its adverse effects on general health, and raising the awareness of society to this problem.

New Approach for The Turbidimetric Determination of Iron(III) in Drug Samples of Different Origins Using Homemade Linear Array Ayah 5SX1-T-1D-CFI Analyser
...Show More Authors

A new Turbidimetric method characterized by simplicity, accuracy and speed for determination of iron(III) in drug samples by continuous flow injection analysis. The method was based on the formation of complex for iron(III) with 8-hydroxyquinoline in presence of ammonium acetate as a medium for the formation of deep green precipitate and this precipitate was determined using homemade Linear Array Ayah-5SX1-T-1D continuous flow injection analyser. The optimum parameters were 2.6 mL.min-1 flow rate using H2O as a carrier, 1.9 mL.min-1 (14 mmol.L-1) ammonium acetate, 2.4 mL.min-1 (14 mmol.L-1) 8-hydroxyquinoline, 60 L sample volume and open valve for the purge of the sample segment. Data treatment shows that linear range 0.1-8.0 mmol.L-1

Determination of the Optimum Conditions for Extracting Polyphenol Ox-idase and Laccase Enzymes From Malva Parviflora and Their Role in The Decolorization of Some Dyes
...Show More Authors

     The current work was undertaken to obtain the crude extract of PPO and laccase enzyme from the leaves of Malva parviflora. All leaves were washed with tap water, then the extraction was performed to acquire the crude extract’s enzymes. One gram of Malva parviflora leaves was homogenized in various volumes of distilled water (1:10, 1:5, and 1:2 w: v). The results showed that polyphenol oxidase and laccase with a ratio of 1:10 (w:v) gave the highest specific activity of 112.3 with 0.394 U/mg proteins. In addition, Malva parviflora leaves were homogenized with several types of buffers with two concentration (0.2 and 0.1 M) for PPO and laccase extraction. These buffers were potassium

Mass Spectrometric Determination OF Radioactive Decay OF 87Rb TO 87Sr IN Some Iraqi Geological Minerals
...Show More Authors

Determination of isotopic composition of strontium and Rubidium in some geological samples was performed by using thermal ionization mass spectrometry. The optimum evaporation and ionization currents were determined for each of strontium and Rubidium, employing double rhenium filament by using faraday cup as detector. The results were compared  with  reference  mater ials (NBS Standards) of Sr and Rb. The

radioactive decay of 87Rb to 87Sr was also determined.

Determination of flow units of Yamama Formation in the West Qurna oil field, Southern Iraq
...Show More Authors

The major objective of this paper is to recognize the flow units of Yamama Formation in the west Qurna oil field, south of Iraq. To attain this objective, four wells namely, WQ-23, WQ-148, WQ-60, and WQ-203 are selected and analyzed. The two techniques hat proposed by some scientists to identify flow units are tested and verified. Results are also enhanced using well logs interpretation and the flow areas are proposed through the studying of the behavior of different well logs. Results of applying the two proposed techniques identify six flow reservoir units for the wells WQ-23, WQ-148, WQ-60, and WQ-203, respectively. This study also shows that the flow reservoir properties in the Yamama Formation improved towards the northeast of the W
