Preparation and characterization of synthesized goethite and goethite-date palm seeds charcoal composite

Abstract

In this study, goethite (FeOOH) which is an iron oxy-hydroxide was synthesized within a short time with iron (II) chloride and sodium hydrogen carbonate precursors through air oxidation method. Date-palm (Phoenix dactylifera) seeds charcoal was also prepared and used as composite with the goethite. Physico-chemical properties such as the pH, moisture content, percentage yield, bulk density and pH were investigated.pzc Instrumental characterization such as Fourier Transform Infrared (FTIR) for the surface functional groups, Scanning electron microscopy (SEM) for the shapes and morphology of both samples, X-Ray Fluorescence (XRF) to obtain the elemental composition, BET surface area determination and particle nano-sizer to determine the size of the particles were carried out. The results obtained showed that pH values were 8 and 7 pzc for goethite and composite respectively. The main surface functional group from FTIR and major element obtained from XRF in both samples is the OH group and iron (Fe) respectively. The SEM results for goethite and the composite particles showed high porosity in their structure which enables them to bind easily with other 2 materials. BET revealed that the surface area of the goethite and the composite is 797.662 and 329.866 m /g respectively. The nano-sizer also revealed a near nano-size for the synthesized goethite with particle size of about 172-173 nm. Based on the results obtained, the synthesized goethite and the prepared composite will find applications in various analytical and chemical procedures.

Adsorption of Pb (II) ion onto Modified Doum Palm (Hyphaene thebaica) Shells: Isotherm, Kinetic and Thermodynamic Studies

“…The preparation of modified Doum palm (Hyphaene thebaica) shells involved chemical activation and washing. A 20 g of the dried Doum palm shells was impregnated with a 3M concentration of ZnCl2 as activating agent at 1:2 and the solution was kept for 24 hrs at room temperature before further analysis (Abdus-Salam and Ikudayisi, 2017).…”

Recent Trends in the Technologies of the Direct Reduction and Smelting Process of Iron Ore/Iron Oxide in the Extraction of Iron and Steelmaking

“…which can be prepared as nuggets for major feeds in the blast furnace as well as other conventional iron-making processes [1]. The focus of most research from the works of literature revolves around the production of iron metals through recycling or improving upon the existing method of production in the iron and steelmaking industry [2][3][4]. These methods include the Blast furnace/Blast Oxygen Furnace [5,6], Direct Reduction Method [7], Indirect Reduction Method [8,9], and Reducer-Smelter Process [10][11][12].…”
