“…The treatment of surfactants from water by advanced oxidation processes (AOPs) has been proven as a promising remediation method for recalcitrant surfactants (Khan et al 2018;Brandão et al 2019;Zhou et al 2019). Different techniques of AOPs currently employed for remediating surfactants are based on electrochemical, electro-Fenton, electroperoxide, and ultraviolet light irradiation.…”

This work comprehensively reviewed the toxicity and risks of various surfactants and their degraded products in the environmental matrices, various analytical procedures, and remediation methods for these surfactants. The findings revealed that the elevated concentration of surfactants and their degraded products disrupt microbial dynamics and their important biogeochemical processes, hinder plant-surviving processes and their ecological niche, and retard the human organic and systemic functionalities. The enormous adverse effects of surfactants on health and the environment necessitate the need to develop, select, and advance the various analytical and assessment techniques to achieve effective identification and quantification of several surfactants in different environmental matrices. Considering the presence of surfactants in trace concentration and environmental matrices, excellent analysis can only be achieved with appropriate extraction, purification, and preconcentration. Despite these pre-treatment procedures, the chromatographic technique is the preferred analytical technique considering its advancement and shortcomings of other techniques. In the literature, the choice or selection of remediation techniques for surfactants depends largely on eco-friendliness, cost-implications, energy requirements, regeneration potential, and generated sludge composition and volume. Hence, the applications of foam fractionation, electrochemical advanced oxidation processes, thermophilic aerobic membranes reactors, and advanced adsorbents are impressive in the clean-up of the surfactants in the environment. This article presents a compendium of knowledge on environmental toxicity and risks, analytical techniques, and remediation methods of surfactants as a guide for policymakers and researchers.

“…To the best of our knowledge, there are few studied on the photocatalytic oxidation of sulfolane [77][78][79][80]. The majority of these studies focused on combining a variety of oxidative methods and also photocatalysis to achieve a desired level of degradation in a photo-reactor.…”

Global economic shifts towards utilization of solar energy provides opportunities for photocatalytic technologies that can harness this abundant source of energy for treatment of organic contaminants. The majority of studies in this area have been performed under artificial light, whereas in this paper, the efficacy of passive photocatalysis was studied under sunlight. Buoyant titanium dioxide (TiO2) coated glass spheres were used to treat 2, 4-dichlorophenoxy acetic acid (2, 4-D), methyl chlorophenoxy propionic acid (MCPP), and 3, 6-Dichloro-2-methoxy benzoic acid (Dicamba) in Killex®, a commercially available herbicide. Furthermore, photocatalytic degradation of sulfolane and a typical naphthenic acid (cyclopentane carboxylic acid—CPA) were also tested under ambient conditions. The results showed 99.8% degradation of 2, 4-D, 100% degradation of both MCPP and Dicamba in Killex® solution, and 97.4% degradation of sulfolane by capturing 3.18 MJ/m2 solar energy. Total organic carbon (TOC) was decreased by 88% and 64% in both solutions, respectively. TOC of the aqueous solution containing 20 ppm CPA was also decreased by 78.4% with 7.8 MJ/m2 energy. Despite the slow kinetics and the temporal variations of sunlight in northern latitudes, the results indicated that passive photocatalysis is a promising approach for treatment of contaminants under ambient conditions.

“…4 Over the years, treatment of sulfolane in various media has been investigated using a variety of physiochemical and biological processes including aerobic biodegradation, advanced oxidation processes, activated carbon adsorption and others. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Amongst the various techniques evaluated to treat sulfolane-impacted water, aerobic biodegradation has indicated promise at both laboratory and pilot scales and has been shown to be an economic and environment-friendly approach for the treatment of large quantities of contaminated groundwater. Most sulfolane biodegradation studies were conducted with slurry or sediments collected from sulfolane-contaminated sites.…”

BACKGROUND Sulfolane has recently emerged as a contaminant of concern in and around oil and gas processing sites in North America and elsewhere. In this research, a comprehensive laboratory study was conducted to investigate the importance of several factors (nutrient levels, aeration methods and inoculants) involved in aerobic biodegradation of sulfolane in groundwater. The aerobic biodegradation of sulfolane was also evaluated under field conditions, which can provide useful information for future field application. RESULTS A lag period of 40–141 h and a zero‐order rate of 0.6–6 mg L−1 h−1 for sulfolane degradation were observed under different laboratory conditions. The aerobic biodegradation rates observed in the field in Alberta, Canada were 4–6 mg L−1 day−1. A C:N:P ratio of 100:5:1 was determined to be suitable for aerobic degradation of sulfolane. The introduction of sediments from sulfolane‐contaminated sites can shorten the lag period from 141 to 74 h. CONCLUSIONS Sulfolane can be effectively degraded in groundwater using aerobic biodegradation in both laboratory and field conditions. A negative correlation was obtained between adenosine triphosphate and sulfolane concentration when it started to degrade. © 2021 Society of Chemical Industry (SCI).
