Polyaniline-derived carbons: Remarkable adsorbents to remove atrazine and diuron herbicides from water.

摘要: Abstract The contamination of water resources by hazardous organic compounds is becoming severe worldwide. In this study, the adsorptive removal atrazine (ATZ) and diuron (DUR), two widely used herbicides, from polyaniline-derived carbons (PDCs) was investigated for first time, under various conditions. A selected PDC, fabricated at optimum conditions, i.e., pyrolysis 800 °C (and labeled PDC(800)), showed remarkable adsorptivity both that is, 7.7 11.3 times maximum adsorption capacity (Q0) ATZ DUR, respectively, compared to activated carbon (AC). Or, Q0 values PDC(800) DUR were 943 884 mg/g, respectively; however, AC only 123 78.0 mg/g, respectively. Moreover, adsorbent had 4.5 3.1 best adsorbent, highest performances, so far, Plausible mechanisms suggested based on porosity in a wide pH range. new reusable via simple solvent washing. Based its performance facile reusability, can be considered promising remove herbicides such as contaminated water.
