“…The newest direction is the sorption-biological remediation of soils, developed by the AO "ESPE" Neorganika "jointly with the Institute of Physical-Chemical and Biological Problems of Soil Science of the Russian Academy of Sciences (Puschino, Moscow region). This direction is associated with the method of soil purification, based on the use of small doses of adsorbent (1-5 % of the mass of soil), which is introduced into the soil together with specially grown microbial strains -destructors of pesticides [4].…”

The article presents the results of studies performed in the period 1991-2016 on the protection of the environment from man-made impact by means of carbon adsorption technologies. However, they were published in publications far from the oil and gas complex and were not known to a wide range of environmental specialists in this industry. There is shown the use of active carbons (carbon adsorbents) for solving environmental problems in the oil industry.

“…3,4 Thus, several technologies such as biodegradation, radiochemical methods, and adsorption have been developed to degrade this compound. [5][6][7] However, their application has been limited due to high cost and time-consuming use, as well as production of secondary wastes of some persistent organic pollutants.…”

Copper (Cu, 1-5 wt%) was loaded onto carbon nanotubes (CNTs) by a simple electrochemical method. The physicochemical properties of catalysts (Cu/CNTs) were characterized by using X-ray diffraction (XRD), transmission electron microscopy (TEM), nitrogen (N2) adsorption-desorption, Fourier transform infra-red spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and electron spinning resonance (ESR). The results showed that the Cu was distributed well on the CNT surface by the interaction of Cu(2+) ions with -OH and -COOH groups on the CNT surface, which preferentially occurred at the defect sites along the CNT backbone. The Cu-O-C bonds formed were found to play an important role in enhancing the photoactivity of the catalysts. The highest number of Cu-O-C bonds possessed by 3 wt% Cu/CNTs demonstrated the best performance in the degradation of p-chloroaniline (96%) under UV light irradiation within 5 h of reaction at 27 °C and under neutral pH conditions. Kinetic studies showed that the degradation followed the pseudo-first order model and the surface reaction was the controlling step. It is believed that these results could contribute to the synthesis of various supported catalysts for various applications.

In this investigation, we isolated from an industrial effluent a bacterial community capable of utilizing p-chloroaniline (PCA) as the sole source of carbon and nitrogen. The isolates were identified as Pseudomonas sp., Achromobacter sp., and Sphingopyxis sp. The bacterial community was employed to set up a continuous system for PCA degradation and ammonium removal. The system consists in two sequential aerobic fixed-bed reactors, for PCA biodegradation and nitrification respectively, and an anoxic reactor for denitrification. Biodegradation process was evaluated by chemical analysis of PCA, chloride and ammonium, and bacterial count. Nitrification and denitrification processes were evaluated by chemical analysis of ammonium, nitrite and nitrate, and nitrifying bacteria count. Bioassays of acute toxicity using the standard organisms Vibrio fischeri, Pseudokirchneriella subcapitata, and Daphnia magna were performed in order to assess detoxification. An average efficiency of 88.5%, expressed as PCA removal, was achieved in the biodegradation process. The maximum PCA removal rate reached 11.7 g/m 3 day. PCA degradation was associated with the release of chloride and ammonium. Ammonium was completely removed by the nitrification/denitrification process. Toxicity was not detected after the biodegradation process.
