“…Solid density, drying weight loss, ash content, and thermogravimetry Impregnation of a carbonized (non-activated carbons) sample http://carbonlett.org FT-IR is mainly used as a qualitative technique for the study of surface chemical functional groups on activated carbons. Carbons are black solid materials that absorb almost all radiation in a range of 360-800 nm and the peaks obtained in FT-IR are commonly a sum of the interactions of the different types of surface groups [13].

Potassium hydroxide-activated carbons (CK21, CK11, and CK12) were prepared from pistachio nutshells. Physicochemical properties of activated carbons were characterized by TGA, pH pzc , Fourier transform infrared spectroscopy, scanning electron microscopy, and N 2 -adsorption at -196°C. The examinations showed that activated carbons have high surface area ranging between 695-1218 m 2 /g, total pore volume ranging between 0.527-0.772 mL/g, and a pore radius around 1.4 nm. The presence of acidic and basic surface C-O groups was confirmed. Batch adsorption experiments were carried out to study the effects of adsorbent dosage, temperature, initial concentration of adsorbate, and contact time on deltamethrin adsorption by activated carbons. The kinetic studies showed that the adsorption data followed a pseudo-second order kinetic model. The Langmuir model showed a maximum adsorption capacity of 162.6 mg/g at 35°C on CK12. Thermodynamic studies indicated that adsorption was spontaneous and increased with temperature, suggesting an endothermic process.

“…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]. A waste material converted to AC is a great potential form of waste recycling [19,20,21].…”

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.

“…The search for these materials could involve existing technologies of food industry. Wastes from these industries can be used to produce the adsorbents [4][5][6][7][8][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26].…”

“…There two ways of getting AC that are known today: chemical [1, 4-6, 10-13, 15, 16, 19, 21-23, 26-28] and physical activation [1,10,15,17,21]. Benefits of chemical activation are one-step process; low activation temperature; short activation time; large yield; high surface; welldeveloped controlled microporosity [28].…”
