“…Ever since Sir Alexander Fleming discovered penicillin in 1928, a large number of antibiotics have been discovered to-date, which has immense contribution in curing human diseases and in veterinary industries. In recent years, it has been reported that a variety of residual antibiotics was detected in the aquatic ecosystem due to misuse and improper disposal of the medicines, and has been regarded as emerging contaminants because of their latent risk and environmental persistence even at low concentrations [1][2][3][4][5][6]. Since most of the antibiotics are tolerant to biological degradation, conventional water treatment facilities adopting biological methods cannot effectively reduce their concentrations [7,8].…”

“…However, skilled technicians and a rigorous maintenance regime are required to handle the unit effi ciently (US EPA 2012 ). Ozonation is not widely practiced commercially owing to its high cost, and the probability of ozone gas emission and its transformation into toxic intermediates (Li et al 2012b ). …”

Pollution and the global health impacts from toxic environmental pollutants are presently of great concern. At present, more than 100 million people are at risk from exposure to a plethora of toxic organic and inorganic pollutants. This review is an exploration of the ex-situ technologies for cleaning-up the contaminated soil, groundwater and air emissions, highlighting their principles, advantages, deficiencies and the knowledge gaps. Challenges and strategies for removing different types of contaminants, mainly heavy metals and priority organic pollutants, are also described.

“…Catalytic wet air oxidation (CWAO) is known as an effective process to treat high concentrated organic wastewaters, which is too concentrated for practical biological remediation and too dilute for economical incineration and recovery (Gao et al, 2013;Hua et al, 2013;Li et al, 2013;Vallet et al, 2013;Wang et al, 2008). CWAO consists in the total oxidation of the organic species present in effluents to CO 2 , N 2 and H 2 O under relatively mild conditions of temperature and pressure, using oxygen or air as the oxidizing source, provided that a suitable catalyst is used (Gomes et al, 2008;Parvas et al, 2014).…”

Non-noble metal Ni with different loadings was coated on precipitated CeO 2 -ZrO 2 support by the sonochemistry method and examined for catalytic wet air oxidation of phenol. The structure of the nanocatalysts was determined by BET, FESEM, XRD, and FTIR analyses. The results showed non-uniform morphology of the nanocatalyst at lower Ni contents changed to homogenous morphology with spherical nano particles at higher Ni contents. While the size of NiO crystals remained constant with rising Ni content, the crystallinity of NiO significantly increased. If the crystallinity of NiO was 100% in 20% wt Ni/CeO 2 -ZrO 2 , the crystallinity of NiO in 5% wt Ni was found to be 41.13%. The average particle size in Ni(15%)/CeO 2 -ZrO 2 was 77 nm in which 85.71% of particle diameters were less than 100 nm. Catalytic wet air oxidation of phenol with different Ni loadings indicated improvement of phenol destruction at higher amounts of active phase. Removal of phenol increased with increasing catalyst loading from 4 to 9.0 g/l but further increase to 10 g/l declined the catalyst reactivity. ª 2014 The Authors.
