A Novel Coated of Mg/Fe Layered Double Hydroxide on Date Palm Stones

Abstract

Mg/Fe layered double hydroxide coated low cost activated carbon (AC-Mg/Fe) was synthesized to be as a novel material by a co-precipitation method. The using of Scanning electron microscope (SEM), Energy Dispersive Spectroscopy (EDS), X-Ray Diffraction Analysis (XRD) and Specific surface area of materials by Brunauer–Emmett–Teller analysis (BET) were employed for characterize the synthesized coated adsorbent. The XRD and SEM displayed that the particles on the surface of low cost activated carbon are regular and good-defined, and the structure of LDHs is typical lamellar. The crystallite size of the coated adsorbent according to the XRD analysis was to be 96.7 nm. The contents of the Fe and Mg after modification increase noticeably according to the EDS analysis. From BET analysis, it was an increasing in the specific surface area of the adsorbent from 22.57 m2/g (before synthesize) to 81.77 cm/g (after synthesize). This analysis resulted in successfully coated Mg/Fe layered double hydroxide (Mg/Fe-LDH) on activated carbon for preparing of a high capacity adsorbent and magnetic sorbent for easy separation by magnetic field.

Synthesis of zinc chloride activated eco-friendly nano-adsorbent (activated carbon) from food waste for removal of pollutant from biodiesel wash water

“…Activated carbon is highly porous in nature and has a wide range of practical applications because of its versatile adsorption capacity (Dabwan et al 2015). Researchers around the globe have utilized bamboo, peach stones, grass, wood, agricultural wastes like coir pith, peanut hull, rice husk, palm trees, palm stones, fruit peel, sugar beet pulp, grain sorghum, wheat husk and industrial wastes for the synthesis of activated carbon (Yalcın & Sevinc 2000;Ramakrishnan & Namasivayam 2009;Abdul-Hameed & Al-Juboury 2020a, 2020b.…”
