In this work, the application of advanced oxidation processes (AOPs) for the removal of antibiotics from water has been reviewed. The present concern about water has been exposed, and the main problems derived from the presence of emerging pollutants have been analyzed. Photolysis processes, ozone-based AOPs including ozonation, O3/UV, O3/H2O2, and O3/H2O2/UV, hydrogen peroxide-based methods (i.e., H2O2/UV, Fenton, Fenton-like, hetero-Fenton, and photo-Fenton), heterogeneous photocatalysis (TiO2/UV and TiO2/H2O2/UV systems), and sonochemical and electrooxidative AOPs have been reviewed. The main challenges and prospects of AOPs, as well as some recommendations for the improvement of AOPs aimed at the removal of antibiotics from wastewaters, are pointed out.

“…As pKa of Eq. (11) is 2.8 [28], therefore CT degradations at the initial pH 6 and 9 were higher than those at pH 3 and unadjusted pH groups. Mora et al also found that trichloroacetic acid degraded faster in pH 6-7 than pH 3-4 in the thermally activated PS system in the presence of formate [17].…”

The thermally activated persulfate (PS) degradation of carbon tetrachloride (CT) in the presence of formic acid (FA) was investigated. The results indicated that CT degradation followed a zero order kinetic model, and CO -2 $ was responsible for the degradation of CT confirmed by radical scavenger tests. CT degradation rate increased with increasing PS or FA dosage, and the initial CT had no effect on CT degradation rate. However, the initial solution pH had effect on the degradation of CT, and the best CT degradation occurred at initial pH 6. Clhad a negative effect on CT degradation, and high concentration of Cl -displayed much strong inhibition. Ten mmol$L -1 HCO -3 promoted CT degradation, while 100 mmol$L -1 NO -3 inhibited the degradation of CT, but SO 2 -4 promoted CT degradation in the presence of FA. The measured Cl -concentration released into solution along with CT degradation was 75.8% of the total theoretical dechlorination yield, but no chlorinated intermediates were detected. The split of C-Cl was proposed as the possible reaction pathways in CT degradation. In conclusion, this study strongly demonstrated that the thermally activated PS system in the presence of FA is a promising technique in in situ chemical oxidation (ISCO) remediation for CT contaminated site.

“…In references [13] and [14] it is assumed that a contribution to the initiation of polymerisation can be made by an aminomethyl radical and the aminohydroperoxide formed from it. They could be formed by fragmentation of the cation radical of DMPT according to [27] or with the participation of a superoxide anion radical [28]:…”

Anaerobic adhesives, fi rst developed in the USA, have been further developed in a number of countries and have been used successfully for the past 5 years in many areas of engineering for sealing, securing, stoppering, and bonding. Their distinguishing features are the single-component nature of their application and their ability to be stored for a long time (over a year) in an air atmosphere and to cure rapidly in the narrow gap between metal surfaces as oxygen is depleted, i.e. under anaerobic conditions [1, 2]. At the same time, anaerobic adhesives are essentially two-component, as the second component is the substrate metal [3].
