To investigate the optimal conditions for the basic decomposition of sunflower seed peels to produce a high-quality carbon precursor, and characterize the physical and chemical properties of the carbon precursor obtained from the decomposition process, one type of nut shell sunflower seed peels was adopted which is characterized by extreme hardness and high lignin content to prepare an activated carbon. The quantity of iodine adsorbed by the experimental material surpassed that of the commercial model, especially at a 1:1 ratio. The experimental material achieved an iodine number of 907 and a methylene blue dye adsorption of 91-indicating superior performance and higher density. Additionally, increasing the proportion of the carbonated material from 0.5 to 2 significantly enhanced the number and property of internal pores, leading to improved adsorption properties. The experimental activated carbon exhibited superior performance compared to commercial models, particularly in terms of iodine number and methylene blue dye adsorption. While the increased KOH ratio led to a decrease in density, it also resulted in a highly effective activated carbon with neutral pH and low density. This suggests that the carbonization process effectively disrupted the original structure of the sunflower seed peels, creating a highly porous material.This study demonstrates that sunflower seed peels, combined with enhanced chemical processing, can produce highly efficient activated carbon. The results indicate significant potential for environmental and industrial applications. However, strategies to reduce moisture content and costs should be explored to maximize the benefits.

This study explores the possibility of modifying the rheological properties of chlorinated asphalt by introducing pyrolyzed polystyrene. Pyrolyzed polystyrene was introduced into the asphalt mixture, resulting in three distinct samples, each containing varying proportions of pyrolyzed polystyrene blended with chlorinated asphalt. Subsequent laboratory tests, conducted included evaluations of ductility, penetration, and softening point. The results indicated significant changes in asphalt properties due to the introduction of pyrolyzed polystyrene. Additionally, the chlorination process also was affected on the thermal properties of the original asphalt. This study has obtained asphaltic samples with rheological properties suitable for various asphalt application, including paving, platinating and mastic accordance to the standard specifications.

The research included a study of the effect of double doping on the electrical conductivity of polyaniline (PANI) after it was prepared by pure aniline polymerization (oxidation polymerization) as a first step, and then doping the polyaniline by monomeric doping with acid solutions of each of the two acids H2SO4 and HCl with different concentrations each separately, then doping Polyaniline monomeric doping with chloride salt (FeCl3, HgCl2, CuCl2, AgCl ) with different weight ratios. The acidic doped polyaniline was doped again with salt, the third step, It is the process of double doping of a polymer using acids and metal salts together. As this process is done by doping the polymer with sulfuric acid at a concentration of (1M) (which gave the highest electrical conductivity), and then re-doping this acid-stained doped form using the metal salt (HgCl2) (which gave the highest electrical conductivity among other ionic dopants) and by weight ratios% (3, 5, 10, 15, 20). The characteristics of (I-V) were measured to show the mechanism of electrical conduction in the polymer using an electrical circuit manufactured locally in the laboratory and by applying different efforts, as the results were shown. The double doping has a clear effect on the electrical conductivity, and it is higher than the electrical conductivity of the un-dopped and monomeric models with acid solutions or metal salts.

Ethylene glycol (EG)is a colorless, odorless, sweet-tasting chemical mainly used as antifreeze which is fatal if ingested. Annonais used as spices and as an herbal medicine (antioxidant) in America countries. Aim of the research was to evaluate the protective role of annonaceae against the Ethylene glycol as toxicity in rabbits. Twenty fiverabbits were divided into five groups: (GI,control group) 5rabbitsuntreated with Ethylene glycol and(GII ) 5rabbits were give 0.75 % Ethylene glycol in drinking water onlyfor 30 days, while (GIII, GIV and GV)15 rabbits were give 0.75 % Ethylene glycol in drinking water and oral supplementation of Annona (flavonoids, glycosides and alkaloids) extracts(100mg /kg Bw) two times daily for 30 days.Blood samples were collected (plain tube & EDTA tube) to clinicalexamination. EG induced significant reduction (20%) in rabbits BW in G II in comparison with GI, GIII, GIV and GV.The result show, AST, ALT, ALKP, TBIL, MDA, SOD,urea,creatinine,globulin andmonocytesin G II were significantly elevated (P=0.05); meanwhile there were significant decrease (P=0.05) in total protein, albumin, A/G ratio, Gpx, CAT, GSH, BP, Hb,WBC and RBC . But after treatment by extracts of Annonasignificant reduction inAST, ALKP, TBIL, MDA,urea,creatinineandmonocytes, while SOD,ALTno significant decrease. Meanwhile there were significant increase (P=0.05) in total protein, A/G ratio, Gpx, GSH, BP, Hb, WBC and RBC.

In the present study, the activation features of phosphoric acid have been investigated using beet molasses as a raw material at 150ºC in production of phosphorized granular activated carbon (PGAC). The quality of the prepared carbon was tested by measuring its iodine number and ability to adsorb methylene blue dye. The density, moisture content, hardness, effective size, and total ash content were also evaluated. The obtained results were compared with a carbon of a commercial grade supplied by the BDH chemical company. The comparison proved that the prepared carbon is of a good quality and comparable to the commercial one. IR analysis showed the (-H 2 PO 3) groups were present on the surface of prepared PGAC which enlarged the pores sizes. The PGAC was used for the sorption of MB dye from aqueous solutions at 25ºC. The equilibrium sorption isotherms have been analyzed by the models Freundlich and Langmuir methods. The Freundlich isotherm had the highest correlation coefficient.

The present study depended on (54) samples of water, nunicipal wastewater (39) samples Tigris river water (north, middle and south) of Mosul city (9) samples and water supply treatment plants (Al-Maa Al-Muwahad & Al-Danadan) (6) samples. Analytical results showed the LAS concentration in nunicipal wastewater samples may vary between (0.67-2.5)mg/L and in Tigris river water (north,middle and south) was found (0.01, 0.35 & 0.9) mg/L respectively. The concentration of some heavy metals (Cu, Cr, Pb, Mn & Fe) was measured using atomic absorption spectrophotometer for the river raw water samples and water supply treatment plants samples. The removal affinity percentage of heavy metals (Cu, Cr, Pb, Mn & Fe) was calculated. Study's results indicated decreasing in heavy metals removal efficiencywith increasing in detergents (LAS) concentration in Tigris river water, this improved (LAS) acts as a dispersion factor for heavy metals in wastewater which prevents its sedimentation and removing. In order to decrease the environmental and health dangers of detergents pollution, wastewater curing by using a special unit of treatment (suggested by the investigators) with four types of granular activated carbon (GAC).
