Objectives. Contamination with heavy metals hasaugmented in last decades due to several factors. So,scientific community has a challenge to develop new andmore efficient methods for contaminants removal.Electroadsorption is one of investigated techniques withpromising results. The main challenge with this techniqueis determination of optimal parameters, such as electrodematerial, time and conditions of adsorption. Material forelectrode for electroadsorption must fulfil some criteria:high electroactive area, low electrical resistance andenvironmental compatibility. For that reason, ourresearch group decided to synthetize a set of new carbonmaterials with high surface area and features than makethem interesting to test them as an electrode material.Methodology. 3 carbon materials were synthetized bysol-gel method using different time and temperatureconditions. All materials were characterized by scanningelectron microscopy and other techniques. FTO glasseswere modified with synthetized materials separately.Electroadsorption of Cu (II) was conducted at roomtemperature. Contribution. In this work we demonstratean easy synthesis of 3 carbonaceous materials with highsurface area capable to remove Cu (II) from watersolution by electroadsorption.
