“…Chlorophenols are widely used in industry (Peng et al., ). The chlorinated compounds are released into the environment in a variety of ways, such as by discharge of phenolic wastewater, the use of pesticides, and manufacture of pharmaceuticals (Fricker, LaRoe, Shea, & Bedard, ; Marković et al., ).…”

Using glucose as cosubstrate, activated sludge that could effectively biodegrade 40 mg/L 2‐chlorophenol was successfully domesticated in sequencing batch reactors. To acclimate the sludge, 2‐chlorophenol was increased stepwise from 0 to 40 mg/L. High‐throughput sequencing revealed that the microbial community richness increased during the first 5 days of acclimation to 5 mg/L 2‐chlorophenol and then decreased after another 20 days as 2‐chlorophenol was increased. The original sludge obtained from a water resource recovery facility had the highest microbial diversity. As the acclimation continued further, community richness and diversity both increased, but they decreased again, significantly, when 2‐chlorophenol reached 40 mg/L. Saccharibacteria_norank, Bacillus, Saprospiraceae_uncultured, and Lactococcus were the dominant bacteria. Bacillus and Pseudomonas were the main known chlorophenol‐degrading bacteria. WCHB1‐60_norank, Tetrasphaera, Comamonadaceae_unclassified, and Haliangium showed poor tolerance to 2‐chlorophenol. Higher bacterial tolerance to chlorophenols does not mean higher degrading capability. The degradation of chlorophenols was not positively correlated with the detected abundance of known 2‐chlorophenol‐degrading bacteria. Practitioner points Activated sludge that could effectively biodegrade 40 mg/L 2‐chlorophenol was successfully domesticated using glucose as cosubstrate in sequencing batch reactors. Saccharibacteria_norank, Bacillus, Saprospiraceae_uncultured, and Lactococcus were the dominant bacteria. Bacillus and Pseudomonas were the main known chlorophenol‐degrading bacteria detected in this study. The degrading capability and tolerance of bacteria to chlorophenols were relatively independent and the degradation of chlorophenols may be the synergistic effect of various bacteria.

“…Chlorophenols are deposited in the environment mainly through the direct discharge of industrial waste [9][10][11]. By estimation, the annual production of chlorophenols is approximately 200,000 tons, and in the US alone, there are about 2,000 tons of chlorophenol compounds wastes in industries dedicated to the production of insecticides, paper, and wood and in petroleum refineries [12][13][14]. Chlorophenols are considered refractory pollutants that when poured into ecosystems can cause serious problems to the environment and to the species that inhabit it, including humans.…”

A gallery of hydrotalcite-type mesoporous materials with different Mg/Al molar ratios were synthesized by the coprecipitation method. The materials were activated by heat treatment to test their activity in the photodegradation of 2,4,6-trichlorophenol under UV light irradiation. The physicochemical properties of the different synthesized and activated materials were determined using XRD, physical adsorption/desorption of N2, FTIR, SEM, DTA, and TGA. Their banned band energy was determined by UV-Vis to identify their potential to be used as a semiconductor in catalytic photodegradation processes. The results of photodegradation tests of 2,4,6-trichlorophenol showed that hydrotalcites have a high degradation capacity, up to 100% for the catalyst of Mg/Al ratio = 2, with a high mineralization capacity of 80%. The degradation capacity of most of the catalysts tested is mainly due to the presence of holes and the formation of superoxide free radicals, which are the determining species within the degradation mechanism.

“…Chlorinated organic compounds (COC) are widely used as raw materials, intermediates or solvents in the chemical and pharmaceutical industries for various applications. [1][2][3][4][5] Most of them are toxic or carcinogenic and have been linked to developmental toxicity problems, and liver, lung and nervous system damage. [6][7][8][9] In recent years, nano-sized zero valent iron (nZVI) has been widely applied to treat a wide range of contaminants due to nZVI being cheap, abundant and non-toxic and possessing excellent chemical, surface and adsorptive properties.…”
