| Description: | According to the EU Directive the maximum permissible concentration of arsenic in drinking water is 10 μg/l. But in many countries (China, Chile, Malaysia, Taiwan, etc.) arsenic content in natural waters is much higher than this level. Four adsorbents were used to determine the influence of preparation conditions on As(V) sorption efficiency applying activated carbon doped by iron oxyhydroxide: birch activated carbon (Sorbent 1); birch activated carbon doped by iron oxyhydroxide (Sorbent 2); birch activated cabon additionally activated by H[2]O[2] and doped by iron oxyhydroxide (Sorbent 3) and birch activated carbon additionally activated by KMnO[4] and doped by iron oxyhydroxide (Sorbent 4). Dopping by iron oxyhydroxide dramatically increased treating efficiency of birch activated carbon. But H[2]O[2] and KMnO[4] are expensive and KMnO[4] is limited to sale due to its presence in precursor list of many countries, including Ukraine. So, additional activation by H[2]O[2] or KMnO[4] dramatically increases adsorbent cost with insignificant increasing of effectiveness. Thus, birch activated carbon doped by iron oxyhydroxide without additional activation and pre-oxidation is the most perspective among these adsorbents. |
