“…This indicates that the AC may probably be an L-type and may have acidic oxides predominating its surface as has been reported by Matos et al (2012). However, the pH values obtained in this study falls within the range of most commercial AC used for adsorption purposes (Erhayem et al, 2016). High electrical conductivity is a desirable characteristic for commercial AC used as electrode material for supercapacitors (Fan et al, 2011).…”

Palm kernel shell and coconut shell are used as a precursor for the production of activated carbon, a way of mitigating the tons of waste produced in Ghana. The raw Palm kernel shell and coconut shell were activated chemically using H3PO4. A maximum activated carbon yield of 26.3 g was obtained for Palm kernel shell and 22.9 g for coconut shell at 400oC, an impregnation ratio of 1.2 and 1-hour carbonization time. Scanning electron microscopy reveals well-developed cavities of the H3PO4 activated coconut shell and Palm kernel shell compared to the non-activated carbon. Iodine number of 743.02 mg/g and 682.11 mg/g, a porosity of 0.31 and 0.49 and the electrical conductivity of 2010 μS/cm and 778 μS /cm were obtained for the AC prepared from the coconut shell and Palm kernel shell respectively. The results of this work show that high-quality activated carbon can be manufactured locally from coconut shell and Palm kernel shell waste, and a scale-up of this production will go a long way to reduce the tons of coconut shell and Palm kernel shell waste generated in the country.

“…In order to respect the effect of DS source on the physicochemical properties and its applications, two raw date stone (DS) samples were collected locally from Howan City and Obarie City, middle south and south of Libya, shown in Fig. 1 [7][8][9]. The samples were washed several times with tap water to remove dirt and impurities present in raw materials, and the rinsed with distilled water.…”

This work focus on the effect of physical and chemical carbonization and activation processes on physicochemical properties of activated carbon from date stone (ACDS) and their applications. Twelve ACDS samples were obtained from two date stone samples at three different temperatures (300, 500, 700 o C) using physical carbonization and activation, and using chemicals (NaCl, H 3 PO 4 , NaOH) at 500 o C. The characterization of these ACDS samples were evaluated using moisture content (MC), pH, bulk density (BD), ash content (AC), conductivity (CD), total dissolved solids (TDS), salinity (SA) and carbon yield (CY), and its potential application on adsorption process as low-cost adsorbent. The CY, BD, MC, CD, TDS and SA of ACDS prepared by physical activating process decreased with increasing temperature, while the pH values increased from 4.70 to 6.74 with increasing activation process temperature from 300 to 700 o C, respectively. The highest Ni(II) ions adsorbed onto ACDS was obtained from ACDS activated with chemical activating process using NaOH at 500 o C. Therefore, ACDS prepared chemically by NaOH is the best to be used in waste water treatment.
