REMOVAL OF HEAVY METALS FROM REFINERIES WASTEWATER

In this study, the adsorption method was investigated for removing vanadium (V+5), nickel (Ni+2) and cadmium (Cd+2) ions from aqueous solutions contaminated with these metals, which simulate the polluting metals of the liquid wastewater of oil refineries in three Iraqi refineries, namely the Kirkuk refinery - Kirkuk governorate in northern Iraq, and the Doura refinery - Baghdad in central Iraq and Al-Shuaiba refinery in Basra Governorate, southern Iraq. Three types of pre-prepared common adsorbents were used, which are activated carbon, alumina, and white eggshells in a batch mode unit. The results obtained from the study showed that 5 was the best acidic function (pH) for removing vanadium and cadmium by using all adsorbent materials, while the acidic function with a value of 6 was the optimum in the case of nickel. Likewise, the equilibrium concentration with the activated carbon only reached 150 ppm for vanadium and cadmium and 100 ppm for elemental nickel. The nickel equilibrium concentration reached 90 and 75 ppm using alumina and white eggshells respectively. The equilibrium concentrations of vanadium were 100 for the rest of the substances. The results obtained also showed that increasing the agitation speed leads to enhancing the removal efficiency within less than 400 rpm and with a best contact time was 150 minute under ambient temperature and with an amount of adsorbent ranged between 0.3 - 0.7 g of different adsorbent.

Synthesis of Cobalt Iron Oxide Doped by Chromium Using Sol-Gel Method and Application to Remove Malachite Green Dye

In the current paper, the nanoparticles of cobalt iron oxide doped by chromium (CIC) of (CrxCoFe2-xO4) formula were prepared by sol-gel method using the nitrate salts of the elements composed of this nanomaterial. The characteristic properties of CIC nanoparticles prepared were determined using X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) in addition to scanning electron microscopy (SEM) and also examination of the surface area (BET). These tests showed that the CIC nanoparticle prepared was in a pure phase, in addition to having various functional groups; moreover their structural framework includes multiple pores, which was the reason for the high surface area, reached to 223.36 m2.g-1. The prepared CIC nanoparticle was applied as an adsorbent to recover the malachite green dye from aqueous contaminated solutions in a batch mode adsorption unit and under different operating conditions. Designing factors used to determine the efficiency of the CIC as an adsorption media for the organic dye included the acidic function (pH), contact time and amount of nanomaterial CIC. The obtained practical results showed that the removal efficiency of the malachite green dye using CIC nanoparticle was 88.519% at 50 ppm of the initial concentration of the contaminated solution and that the percentage removal was directly proportional to the amount of adsorbent, contact time and acidic function.

A COMPARATIVE STUDY OF THE TYPE OF GROUNDWATER FOR WESTERN MOSUL REGIONS

Three water springs were selected in the western part of the city of Mosul (AinQana belongs to Al-Ayadiyah sub-district, Ain Abu Maria village, and AinSubashi in the center of Tal Afar district) to study some physical and chemical characteristics (temperature, electrical conductivity, acidic function, as well as negative and positive ions) and the biological characteristics of algae. The results of the study showed that the change in water temperature was little during the study period, and the highest value of the electrical connection reached (2557, 2488, and 1817) microsiemens / cm in Subashi, Qana, and Abu Maria sites, respectively. Whereas, the average dissolved oxygen concentration ranged between (0.0 to 3.6) mg / L at Qana and Subashi sites respectively. The total basal values ranged between (128) mg / L as CaCO3 at the site of Qana and (154) mg / L as CaCO3 at the site of Subashi. The results showed that the sodium concentration values were greater than the potassium concentration values in the three sites. Sixteen species of algae that belong to the algae section were diagnosed as bluish-green algae, green algae, and red algae. Oscillatoria was diagnosed in AinQana and the absence of the species belonging to the two algae sections, green and red algae in AinQana.

Promotional Effect of Pd Addition on the Catalytic Activity of Composite Pt-Pd/AlSBA-15–β Catalyst for Enhanced n-Heptane Hydroisomerization

Hierarchical AlSBA-15–zeolite materials were utilized as a supports for preparing hydroisomerization catalysts. Detailed consideration was given to: (i) the effect of the zeolite type introduced into AlSBA-15–zeolite composites (where zeolite is β, mordenite or ZSM-5) as well as (ii) the promotion effect of Pd addition. The composites showed higher activity in isomerization as compared to Pt/AlSBA-15. The enhanced isomerization efficiency were explained by the appropriate metallic and acidic function as well as suitable transport properties. The modification of the hydrogenating function by Pd incorporation increases the hydroisomerization efficiency of Pt-Pd/AlSBA-15–β catalyst. Over bimetallic Pt-Pd/AlSBA-15–β, the high yields of isomers (68 wt%) with respect to 50 wt% for a control catalyst. The most promising Pt-Pd/AlSBA-15–β catalyst allows to improve research octane number from 0 to the 74 value.
