Abstract

In the work the results of electron microscopic examination of samples of activated carbon, prepared from almond shells show that their structures have a developed porous surface. According to the results of semi-quantitative elemental analysis of the adsorbents under study by the method of energy dispersive X-ray spectroscopy (EDAX), it was found that the adsorbent based on almond shells has the highest carbon content (94%). The activated carbon prepared from almond shells has the following characteristics: moisture content - 7.7%, total pore volume on water  - 0.71 cm3/g, pH of the aqueous extract - 7.2, bulk density - 282 g/dm3, adsorption activity on iodine - 63.4%, specific surface area - 882 m2/g.
