Adsorption Performance Study of Atrazine onto Activated Carbon Fiber

The research used activated carbon fiber (ACF) as adsorbent to remove atrazine, a kind of herbicide. It set a series of static adsorption experiments under different solution temperature, pH value and initial concentration to get a optimum adsorption condition. The experiment shows that the optimum pH for the removal of atrazine is 7. The adsorption rate is highest at 20°C. The adsorption rate decreases while the initial concentration increases.

Adsorption Amount

The activated carbon fiber (ACF) was treated by different concentration nitric acid (HNO3) and hydrogen peroxide (H2O2) oxidization to enhance its adsorption capacity to hexavalent chromium (Cr6+) ion. The adsorption amount and adsorption kinetics of Cr6+ion on ACFs, and the surface chemical groups were investigated. The results showed that the modified ACFs with 1% HNO3and 10% H2O2had a better adsorption capacity, respectively. The adsorption amount of ACFs was affected strongly solution pH value, and decreased significantly with increasing of the pH value. The adsorption kinetics indicated that the adsorption rates of Cr6+ ion on different modified ACFs were well fitted with the pseudo-second-order kinetic model. After 1% HNO3and 10% H2O2modification, respectively, the total acidic oxygen-containing groups on ACFs surface had an increase obviously, which might be enhance the adsorption amount of Cr6+ion on ACFs.

Activated Carbon Fiber was use to treat aniline wastewater. Influencing factors，such as pH value ，salinity were studied and dynamic conditions of concentration and flow adsorption effects were also studied. Adsorption isotherm, dynamic curves and dynamic adsorption breakthrough curve were drawn. The results indicated that the salinity of the solution will affect the adsorption results and concentration in the same circumstances, time was 9 min, pH neutral in better conditions adsorption, adsorption capacities were determined to be 72 mg/g .Under dynamic conditions，with increasing concentration and velocity, the initial penetration point ahead．

Methylene Blue Degradation

Activated carbon fiber (ACF) supported TiO2photocatalyst was prepared by sol-gel-adsorption method. The state of TiO2supported on the ACF was observed using a scanning electron microscope. Photo catalytic activity of the catalyst was evaluated by degradation of methylene blue in water, and the ways in which the efficiency of methylene blue degradation was influenced by TiO2load content and pH value were investigated. The supported catalyst shows cooperative effect of ACF adsorption and TiO2catalytic activity, and the catalytic activity of the supported catalyst was basically unchanged after using for four times.

Poly Vinyl Pyrrolidone

The poly (vinyl pyrrolidone) (PVP)/Cobalt Acetate Composite nanofibers were prepared by electrospinning method. Then we got Co3O4-activated carbon fiber (ACF) from PVP/Cobalt Acetate composite nanofibers after preoxidation, carbonation and activation. Study the effect of different adsorption conditions on the adsorption rate of low concentration SO2. The SEM, TG-DTA, XRD, FT-IR and BET analysis methods is used to characterize. The results show that the specific surface area of Co3O4-ACF obtained reach 1238.5 m2/g, and it contains Co3O4 after carbonation. The adsorption rate can reach 69.0%, when the concentration of SO2 is 1.0 μg/mL, adsorption temperature is 20, and adsorption time is 10 minimum.
