“…This is higher than the reported value for the magnetic separation by Du et al [30], who synthesized magnetic activated carbon (AC/Fe 3 O 4 ) with iron contents of 5%, and reported that the saturation magnetization was 0.3 emu/g. In contrast, Khaledi et al [31] reported that the saturation magnetization of magnetic activated carbon is around 13 emu/g at room temperature. All the above results confirmed the successful synthesis of MPHAC.…”

The compound 4-chlorophenol (4-CP) is known to be a highly toxic compound having harmful effects on human health and the environment. To date, the removal of 4-CP by advanced oxidation processes (AOPs) has attracted tremendous attentions. The persulfate-based AOPs show higher oxidation, better selectivity, wider pH range, and no secondary pollution compared to the traditional Fenton-based AOPs. Carbon materials with low cost and chemical stability are useful for the activation of persulfate (PS) to produce reactive species. Herein, we magnetized activated carbon synthesized from pomegranate husk (MPHAC). By using 4-CP as a model organic pollutant, tests of the activation of PS via MPHAC for the removal of 4-CP were performed. Batch processes were carried out to study the influence of different parameters (initial solution pH, catalyst dose, PS dose, and initial 4-CP concentration) on the adsorption of 4-CP on PHAC with ferric oxide (Fe3O4-PHAC). The results show that under the obtained optimal conditions (MPHAC dose: 1250 mg/L, PS dose: 350 mg/L, solution pH 5, an initial 4-CP concentration of 100 mg/L, and a contact time of 60 min), a 4-CP removal factor of 99.5% was reached by the developed MPHAC/PS system. In addition, it was found that reusing MPHAC in five successive cycles is feasible because the catalyst in the last cycle kept exhibiting a high potential for 4-CP absorption, indicating the economically viable procedure. Therefore, this study provides a comprehensive understanding on the degradation of 4-CP by the magnetized activated carbon persulfate system.

“…Increasing the area of adsorption specific surface that can be achieved by applying corrective methods such as loading nanoparticles on the activated carbon surface is one of the efficient factors for increasing the removal yielding adsorption methods [ [29] , [30] , [31] ]. Among the nanoscale materials that have shown good efficiencies in wastewater and water treatment, some examples can be mentioned, such as membrane filters, zeolites, carbon compounds, metal oxides, metal nanoparticles, etc.…”

“…The TC is not entirely metabolized by human and animal organisms, like other antibiotics, and about 90% of the ingested TC is eliminated through the urine. Therefore, TC can form a toxic residue and encourage the contamination by pathogenic organisms if it is released into soil or aquatic ecosystems without receiving an effective pre-treatment [12,13]. According to the findings of recent studies, the presence of tetracycline antibiotics in the environment prevents various terrestrial and aquatic species from growing.…”

In this specific study, the elimination of antibiotics from wastewater accomplished by the process of adsorption as tetracycline serves as the pollutant of interest and commercial activated carbon (AC) as an adsorbent for removal of pharmaceutical micropollutants. The extremely porous nature, high adsorption effectiveness, low cost, and environmentally favourable qualities of activated carbon led to its selection as the material of choice for the investigation. In this work, the adsorption of tetracycline by activated carbon that had been manufactured commercially was investigated. Throughout the batch investigation, the following parameters were held stable: time, pH, adsorbent concentration, adsorbate concentration, and temperature -25º C. Experimentation revealed that the optimum removal effectiveness of 90% could be attained when the pH was kept in the acidic range (between 3 and 7), the contact period is 1 hour and the adsorbent dose is 5 mg per 20 ml. The Langmuir Isotherm curve provided the most satisfactory explanation for the experimental results. The specific study focuses on the analysis of potentiality of the prepared activated carbon in removing pharmaceutical pollutants in wastewater which is not being experimented much. The method was tried on real time sample and was found effectual with a removal efficiency of 87%.
