Adsorption of Malachite Green and Methyl Green on Cow bone

The animal bone meal prepared from the Cow bone has been investigated as a low cost solid adsorbent used for the removal of the hazardous Malachite Green (MG) and Methyl Green (MeG) from wastewater. It was proved that the concentration used was 200ppm as adsorption of MG and MeG dyes. The study was carried out in a batch system to optimize operation variables: working temperature, time and pH for the same adsorbent quantity of bone ash dye solution. This procedure is particularly suitable and has low cost system for purification of wastewater from MG and MeG at relatively short period of time.

Extraction and Determination of Chemical Ingredients from Stems of Silybum Marianum

High performance liquid chromatographic (HPLC) and Inductively coupled plasma (ICP-OES) have been used to analyze the extracts of Silybum marianum (milk thistle) stems for carbohydrates, flavonoid, phenolic acids, Fatty acids, amino acids, flavonolignans and metal ions content. Proximate compositions of milk thistle showed high carbohydrate content especially fructose, high ratio of unsaturated to saturated fatty acid content, a high ratio of essential amino acids especially histidine, and highest ratio of the biologically active flavolignin silybin A. The active antioxidant ingredient coumaric acid showed a highest concentration compared to other phenolic acids and analysis of metal ions showed that Si and Al was the major elements present in the stems of the herb.

Compared levels of specific divalent trace elements in hyperlipidemia and hepatitis sera patients

Patients with hepatitis infection can also have hyperlipidemia. Sera of both hepatitis (40) and hyperlipidemia (40) were collected from the central lab of Sulaimaniyah-Kurdistan region/ Iraq. Age, sex, duration of infection, medication used and lipid profile using computerized database program, as characteristics information of patients were done.  The levels of Cr, Cu, Zn, Mn, V and Se were determined in sera of both patients and compared with healthy controlled (n=30), using Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). Hepatitis samples yielded concentration in ppb of (7.34±0.01) Cr, (171.7±2.51) Cu, (138±3.41) Zn, (1.309±0.99) Mn, (184.7±6.12) V and (218.9±3.14) Se respectively, while hyperlipidemia samples yielded concentration (ppb) of (5.22±0.45) Cr, (197.01±2.34) Cu, (160.3±4.01) Zn, (0.068±1.91) Mn, (247.01±0.65) V and (185.5±3.11) Se respectively. Controlled samples reflects the following concentrations (ppm),  (5.324±1.34) Cr, (131.2±4.34) Cu, (216.6±0.83) Zn, (0.024±1.75) Mn, (235.3±0.18) V and (223.2±3.15) Se  respectively.The aim of the study focused on evaluating metal ions physiological role in the body, and as liver was responsible for synthesizing lipid , thus lipid profiles where suggested to be investigated along the study.

Some Biochemical and Hematological Parameters among Petroleum and Cement Factory workers in Sulaimaniyah City/ Kurdistan/ Iraq

The objective of the current research was to study any alteration in the biochemical and hematological parameters among exposed workers in Petroleum and Cement Factories located in the Bazian basin northwest Sulaimaniyahcity,Iraq .we found  a significant increase  in the average BLL and serum iron values among cement and petroleum refining workers(11.3 µg/dL)and(173 µg/dL)  successively .As well among the studied groups the workers at Mass CF had the highest BLL (15.5 µg/dL) and serum iron(216 µg/dL). An increase in the average values of serum creatinine and AST levels and a significant decline in mean values of ALP among the workers, while, no significant difference were found between other studied biochemical parameters .The hematological analysis revealed a significant increases in the values of RBC, HCT and MPV, in addition to, a decrease in MCHC. Oppositely, no significant differences were found between other blood cell parameters. Keywords: Petroleum and Cement Factories toxic dusts and fumes.

The High Efficiency of Anionic Dye Removal Using Ce-Al13/Pillared Clay from Darbandikhan Natural Clay

Natural clay from Darbandikhan (DC) was evaluated in its natural form, after acid activation (ADC), and after pillaring (PILDC) as a potential adsorbent for the adsorption of methyl orange (MO) as a model anionic dye adsorbate. The effect of different clay treatments was investigated using X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), Scanning Electron Microscope (SEM) and Fourier-Transform Infrared Spectroscopy (FT-IR), and N2 physisorption analysis. Both acid activation and pillaring resulted in a significant increase in adsorption affinity, respectively. The adsorption favored acidic pH for the anionic dye (MO). The adsorption process was found to follow pseudo-second-order kinetics with activation energies of 5.9 and 40.1 kJ·mol−1 for the adsorption of MO on ADC and PILDC, respectively, which are characteristic of physical adsorption. The adsorption isotherms (Langmuir, Redlich-Peterson and Freundlich) were fitted well to the experimental data. The specific surface area of the natural clay was very low (22.4 m2·g−1) compared to high-class adsorbent materials. This value was increased to 53.2 m2·g−1 by the pillaring process. Nevertheless, because of its local availability, the activated materials may be useful for the cleaning of local industrial wastewaters.</jats:p
