“…Adsorption onto AC has several advantages over other water treatment methods, primarily as a very simple technology and more efficient in removing high molecular weight compounds from aqueous matrix (Erabee et al, 2017b). Nowadays, good source for AC preparation is agricultural material because of low cost and availability 5 (Erabee et al, 2017c). The most widely used precursor for production of AC is jute and coconut fibre 6 , apricot stone 7 , coconut husk 8 , and rice husk 9 .…”

Highly porosity characterized activated carbon (AC) was achieved using agricultural waste as raw material used as adsorbent to treat wastewater through removal of ammonia nitrogen (NH-N) and hexavalent chromium (Cr (VI). The preparation method of AC included using zinc chloride as activation agent. Characterizations of the porosities of AC preparations were performed using N 2 adsorption-desorption to ascertain surface area and pore volume. Existing groups on the AC surfaces were resolved using Fourier Transform Infrared Spectroscopy (FTIR) analyses. Scanning electron microscopic (SEM) was used to asses AC morphologies. Maximal surface areas of AC preparations were discovered to be 1190.41 m 2 /g at activation temperatures of 700 o C. Adsorption isotherm was analyzed using two models Langmuir and Freundlich. The kinetic study was represented through Pseudo first order and pseudo second order.

“…Several studies in recent years have aimed to produce more efficient materials that have lower costs and widely available [3,4]. Because of their availability and abundance, agricultural products are considered an excellent source to produce AC [5]. The most commonly used raw materials among these agricultural byproducts were palm of date [6,7], palm oil waste [8,9,10], woods [11,12,13,14], coconut shell [15,16,17], bagasse [18].…”

Abstract. This study aimed to use sago palm bark to formulate a new adsorbent activated carbon (AC) contains highly surface area through physicochemical method via ZnCl2 activation. Conduction of the activation process was performed at varying impregnation ratios (0.5-2.0). Thermal decomposition was determined using thermogravimetric analysis (TGA). Porosity characterizations of AC were conducted by using N2 adsorption-desorption in order to characterise properties like pore volume, surface area, and micropore volume. To detect the presence of functional groups which were found on the surface of AC, Fourier Transform Infrared Spectroscopy (FTIR) analysis was utilised. Morphology of AC was determined using scanning electron microscopy (SEM) and X-ray spectroscopy (EDX). Experimental results showed that maximum AC surface area was 1737 m 2 /g. Activation temperature was revealed to be 700 o C, with chemical impregnation ratio of zinc chloride to a precursor equal to 1.5/1.
