Sissakian f.khajeek@ukh.edu.krd Dalyia A. Hamoodi d.hamoodi@ukh.edu.krd Hassan O. Omer h.othman@ukh.edu.krd Sazan A. Nyazi s.abdealradh@ukh.edu.krd <p>The Pila Spi Formation is exposed in Permam Mountain forming its carapace, and continuous ridges for few hundreds of&nbsp;kilometers. The rocks of the formation are mainly dolomitic limestone, dolomite, and limestone with various proportions.&nbsp;The thickness of the formation in Permam Mountain is about 100 m. Nine samples are collected from the Pila Spi Formation&nbsp;along a recently road cut across Permam Mountain. The sampling interval varies from 10 to 15 m. The collected samples&nbsp;were subjected to X-ray fluorescence (XRF) spectroscopy test to indicate the percentages of the main oxides in the samples.&nbsp;The results showed that the chemical composition of samples No. 1 and 9 meet the Iraqi standards for cement industry,&nbsp;whereas the remaining samples (Nos. 2–8) do not meet the Iraqi standards, and their total thickness is 80 m. To evaluate the&nbsp;suitability of the exposed rocks for cement industry in the sampled section within the Pila Spi Formation, different ratios of&nbsp;sample No. 1 were mixed with different ratios of a sample called sample No. A, it represents a mixture of samples No. 2–8.&nbsp;The mixing ratios are: (Sample No. 1/sample No. A) 50/50, 60/40, 70/30, 80/20, and 90/10. The same procedure was&nbsp;repeated for Sample No. 9. Another attempt was performed by mixing equal ratios of samples Nos. 1 and 9 with the same&nbsp;performed ratios with sample No. A.The chemical compositions of the samples were indicated using XRF test. The results&nbsp;showed that the best mixing ratios for the cement industry are 90:10, 80:20, and 70: 30 (samples Nos. 1+9: sample No. A).</p> 2019-03-01T00:00:00+03:00 ##submission.copyrightStatement## https://journals.ukh.edu.krd/index.php/ukhjse/article/view/79 Synthesis of Zeolite Na-LSX from Iraqi Natural Kaolin using Alkaline Fusion Prior to Hydrothermal Synthesis Technique 2019-04-18T21:24:17+03:00 Ali Mohammed Salih shwangeology@yahoo.com Craig Williams c.williams@wlv.ac.uk Polla Khanaqa drpolla@hotmail.com <p>The synthesis of zeolite materials by hydrothermal transformation of kaolin using an alkaline fusion prior to hydrothermal synthesis method was investigated. The kaolin clay used in the present investigation was supplied from Iraq. The physical and chemical characterization of&nbsp; the&nbsp; starting kaolin and produced zeolite Na-LSX samples were carried&nbsp; out&nbsp; using&nbsp; different analytical techniques such as Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), X – Ray Diffraction (XRD), X – Ray Fluorescence (XRF), Thermogravimetric Analysis (TGA), Fourier Transform Infrared (FT-IR) Spectroscopy and Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES). An alkaline fusion method was introduced prior to the hydrothermal treatment while kaolin clay powder was mixed manually with NaOH powder (ratio = 1/1.2 in weight). The metakaolinisation phase was achieved by calcining the mixture in air at 600 <sup>o</sup>C for 1hr. The result from this route shows that zeolite Na-LSX with cubic rounded edge crystal habit have been successfully synthesised. Finally, The kinetic study indicated the suitability of the zeolite Na-LSX for the removal of Cu<sup>2+</sup>, Fe<sup>3+</sup>, Pb<sup>2+</sup> and Zn<sup>2+</sup> ions from synthetic wastewater.</p> 2019-03-12T00:00:00+03:00 ##submission.copyrightStatement##
