EVALUATION THE PRECISION OF " DOCTORE TEST" FOR MERCAPTANS DETECTION IN PETROLEUM PRODUCTS BY SULPHIDE ION-SELECTIVE ELECTRODE

Mercaptan sulphur in petroleum products ( Motor fuel, kerosene, aviation fuel ,….etc) were detected with standard test method of British Institute of Petroleum ( IP) that marked by the number IP-30 . The detection of this method was qualitatively and the precision has not been established. In this research a précised results were tabulated for the IP-30 test method, using sulphide ion selective electrode. A comparable results of quantitative value for mercaptans of IP-30 test method now are available

Banana Peel as Removal Agent for Sulfide from Sulfur Springs Water

Banana peel which consider as fruit waste has been tested  for the removal of total sulfide from spring water in Heet area, Iraq. The chemical composition of peels was investigated. The results  show that the composition consists of  Sodium ,Potassium, Calcium ,Manganese and Phosphate and concentrations of these contents were 18.2mg/g, 62mg/g,15.4mg/g ,48mg/g and 0.37 mg/g , respectively. The alkalinity of peels was 5.2 mg/g and the moisture content was 5.8 % . The treatment efficiency was studied as a function of the retention time and  concentration of sulfide ion .The maximum sorption for sulfide was found to be 97% and it was nearly effective as activated carbon. As a result of the removal process , the concentrations of  some common anions ,cations and heavy metals (Mg+2,Ca+2,Na+,So4-2,cl-Po4-2, Cr, Fe, Ni, Cu and Zn) decreased ,the concentrations of K+ and Mn increased . Increasing of concentrations of K+ and Mn is attributed to their high content in the banana peels. A slight increase in pH of the treated water (6.5 – 7.5). This study revealed that  the treatment of water using the banana peel is most effective for removal of hydrogen sulfide from sulfur  spring water.

Estimation of Selected Essential Metals in Ginger (Zingiber officinale) and Roselle (Hibiscus sabdariffa)

Zingiber officinale and Hibiscus sabdariffa are common medical plants used in traditional medicine. The mineral elements (Se, Zn, Cu, Fe, Ca,K, Mg and Na) have played a major part in the health and battling sicknesses in the human body. The aim of this study is to estimate the mineral composing, Zingier officinal, Zingier officinal and Hibiscus sabdariffa which would be an important promotion vantage in human health, despite the fact that the characterization of the components is somewhat difficult. The analysis of mineral composition of these plants is carried out by using inductively Coupled Plasma- Mass spectrometry. The finding of this study shows that the level of the elements in, Zingier officinal are 345.7, 7012.7, 2444.7, 685, 8283, 67722, 12260 and 2520 μgkg for Se, Z, Cu, Fe, Ca, K, Mg and Na, respectively. The level of Se, Zn, Cu, Fe, Ca, K, Mg and Nain Hibisus sabdariffa are 55.7, 3052, 2288, 120, 112071, 88690, 27822 and 2229 μgkg, respectively. Moreover, the results of this study suggest that Ginger and Roselle could be utilized as enhancement nourishment or diet improvement particularly in the lower protein diets

AN ENVIRONMENTAL STUDY OF CHEMICAL AND PHYSICAL POLLUTANTS IN EUPHTARES RIVER WATER IN RAMADI AND FALLUJAH .

:This research include study about the contamination of environment that outcome from public efficiencies and humanity activities on the quality and context of Euphrates river in Ramadi and Falluja. The physical study showed that the turbidity, electrical conductivity exceeding the allowable values. The Total suspended solids within the allowable values.The Chemical study showed that the river has neutral properties tended to slightly basic. Total hardness, Calcium and Magnesium were exceeded allowable values ,while bicarbonateWithin the allowable values. It was noted that the values of Sodium and Potassium was high but did not exceed the allowablevalues, Iron average was Within the allowable values.The study has shown that sulphate ion values was exceed the allowable values, while the average for chloride ions fluoride , sulphide within the allowable values . It was also noted that the concentration of Heavy metals and Trace elements were within the allowable values, except for Lead and Cadmium and copper was exceed the allowable values in some study sites

STUDY OF SOME BACTERIAL POLLUTANUTS IN EUPHRATES WATER AND THE LAKES OF THERTHER AND HABBANIAH

ABSTRACT:This research included a study about the pollution of environment that out came from public efficiencies and humanity activities on the quality and context of Euphrates river from the Ramadi entrance city to its end in Falluja city involving Habbanyah and Therthar lakes. This study included some bacterial pollution involving the Total Plate Count of the aerobic microbes in addition to isolation and identification of some bacteria that present in the Euphrates river and Habbanyah and Therthar lakes and Dissolved Oxygen and the rate of Biological Oxygen Demand. The results have shown an average allowable values of dissolved oxygen were (7.7) mg/L and (4.67) mg/L the biological oxygen demand which was exceeded the allowable values average. Microbial study showed that the total aerobic bacteria which have recorded different results as it reached aminimum levels in some sites (F1 station (70 CCm3) and maximum levels in others (F2 station) (314×104 CCm3). The results of isolation and identification of bacteria have shown the presence of the follwing genera :Enterobacter (24%) ،Klebsiella Pneumoniae (17.6 % ) ،Pseudomonas spp (16.2%) ، Citrobacter (12.5%) ، Escherichia coli (12.1%) ،Proteus mirabilis (5.5)، Salmonella spp (5%) Shigella spp (3.7%)، Flavimonas Oryzihabitas (2.8%) . Enterobacter spp was the dominant genus compared with others bacteria have indicated surely the organic and microbial pollutions of the Euphrates water at the studied sites
