Production of Biologically Activated Carbon from Orange Peel and Landfill Leachate Subsequent Treatment Technology

Abstract

In order to improve adsorption of macromolecular contaminants and promote the growth of microorganisms, active carbon for biological wastewater treatment or follow-up processing requires abundant mesopore and good biophile ability. In this experiment, biophile mesopore active carbon is produced in one-step activation with orange peel as raw material, and zinc chloride as activator, and the adsorption characteristics of orange peel active carbon is studied by static adsorption method. BET specific surface area and pore volume reached 1477 m2/g and 2.090 m3/g, respectively. The surface functional groups were examined by Fourier transform infrared spectroscopy (FT-IR). The surface of the as-prepared activated carbon contained hydroxyl group, carbonyl group, and methoxy group. The analysis based on X-ray diffraction spectrogram (XRD) and three-dimensional fluorescence spectrum indicated that the as-prepared activated carbon, with smaller microcrystalline diameter and microcrystalline thickness and enhanced reactivity, exhibited enhanced adsorption performance. This research has a deep influence in effectively controlling water pollution, improving area water quality, easing orange peel waste pollution, and promoting coordinated development among society, economy, and environment.

Mechanical and microstructural characterization of aluminum melted with alternative method

“…The peak at 1843 cm −1 belongs to the nonsymmetric vibration absorption of C=O, and the band between 1410 and 1890 cm −1 could be attributed to the antisymmetric stretching vibration absorption of C=O. In addition, there is a C-H symmetric stretching vibration peak at 2952 cm −1 [27]. These results support the presence of impurities of carbon as shown in EDS analysis in the aluminum structure.…”

Blue corn (Zea maysL.) with added orange (Citrus sinensis) fruit bagasse: novel ingredients for extruded snacks

“…In the extrudates, the 1648 cm −1 band diminished in intensity and the 1539 cm −1 band disappeared, possibly indicative of corn starch protein denaturation in response to temperature. A signal appeared between 1023 and 1049.3 cm −1 , which is similar in all spectra to C-O vibration, and which indicates the presence of cellulose and hemicellulose (Zhigang, Wei, Fangying, & Zhongrong, 2014). This signal corresponds to fiber in the corn pericarp and the orange peel.…”
