This study was focused on investigation of the adsorption property of micronized carbonaceous adsorbent for odorant dimethyl sulfide. Adsorption experiments were also conducted for the adsorption of dimethyl sulfide by chemically-modified carbonaceous adsorbent for comparison. It was shown that the adsorption capacity of micronized carbonaceous adsorbent increased by 94% compared with pristine powdered activated carbons (PACs), and increased by 42% compared with chemically-modified PACs. The micronized carbon demonstrated not only an enhanced adsorption performance for dimethyl sulfide, but also an environmentally-friendly adsorbent without secondary pollution.

Abstract In the present work, an attractive and creative adsorbent derived from sewage sludge was freshly fabricated via pyrolysis technology, followed by modification for improving the absorptive ability. First, the (NH4)2S2O8 modified pyrolytic sludge (MSAP) was selected from 19 modified pyrolytic sludges for the highest removal efficiency and adsorption capacity for methylene blue (MB). Then, the adsorption performance for MB of MSAP was compared systematically with the pristine adsorbent (MSDW) by batch adsorption experiments. The main conclusions were that the adsorption process was better fitted with the Langmuir model, and the maximum adsorption capacity (qmax) of MSAP was observed to be 149.05 mg g−1. Moreover, the adsorption kinetics data showed a good fit with the pseudo second order model; when the addition of MSAP was 1.0 g·L−1, the rate constant was 0.05 g·mg−1·min−1, which was far greater than that of the other modified adsorbents.

Enhanced Adsorption

In this study, a novel 2-vinylpyridine functionalized magnetic nanoparticle (Mag-PVP) was successfully prepared. The prepared Mag-PVP was characterized by transmission electronic microscopy (TEM), Fourier transform infrared spectrophotometry (FT-IR), vibrating sample magnetometry (VSM) and thermogravimetric analysis (TGA), and was used for the adsorption of bisphenol A (BPA) from aqueous solutions. Mag-PVP, which is composed of Fe3O4 nanoparticles and poly divinylbenzene-2-vinylpyridine (with a thickness of 10 nm), exhibited magnetic properties (Ms = 44.6 emu/g) and thermal stability. The maximum adsorption capacity (Qm) of Mag-PVP for BPA obtained from the Langmuir isotherm was 115.87 mg/g at 20 °C, which was more than that of Fe3O4 nanospheres. In the presence of NaCl, the improved adsorption capacity of Mag-PVP was probably attributed to the screening effect of Mag-PVP surface charge and salting-out effect. In the presence of CaCl2 and humic acid (HA), the adsorption capacity of BPA decreased due to competitive adsorption. The adsorption of BPA by Mag-PVP increased slightly with the increase in pH from 3.0 to 5.0 and obtained the largest adsorption amount at pH 5.0, which was probably attributed to hydrogen bonding interactions. Moreover, in actual water, Mag-PVP still showed excellent adsorption performance in removing BPA. The high adsorption capacity and excellent reusability performance in this work indicated that Mag-PVP was an effective adsorbent for removing BPA from aqueous solutions.
