“…It is possible to observe that the decomposition was performed in two stages: via a rapid first-stage (up to 2 min) followed by a slow second-stage (from 2 min to end). This profile of degradation was found in literature and had been recognized in various Fenton processes [25][26][27][28]. During the first 2 min of the reaction, rapid pollutant degradation is attributed to high OH concentrations, as a result of greater amounts of Fe 2+ catalyst in solution that reacts with H 2 O 2 .…”

“…During the first 2 min of the reaction, rapid pollutant degradation is attributed to high OH concentrations, as a result of greater amounts of Fe 2+ catalyst in solution that reacts with H 2 O 2 . At the second stage, Fe 3+ ions were combined with H 2 O 2 to produce weaker oxidant radicals compared to OH, in addition to their slower rate of production [27].…”

“…In the UK, the consumption of ACT with and without prescription was about 3.5 billion of 500 mg tablets in 2000. According to previous studies [18], about 58-68% of ACT is excreted from the body when ingested in therapeutic dosage. So, the concentration of ACT can be significant in wastewater and water resources similar to other pharmaceutical compounds.…”

A B S T R A C TThe efficacy of NH 4 Cl-induced activated carbon (NAC) in removing acetaminophen (ACT) as a model of non-steroidal anti-inflammatory pharmaceutical compounds in aqueous solution is investigated in this study. The experiments were performed in different conditions of solution pH, contact time, initial concentration, adsorbent concentration, and solution temperature to the adsorption of ACT on NAC. The results showed that ACT adsorption onto adsorbent was not pH-dependent in the range of 2-9; but, at higher pH values, the removal efficiency was significantly decreased. Adsorption of ACT by NAC followed pseudo-second order kinetics, and the equilibrium adsorption data best fitted the Langmuir isotherm. The maximum capacity was 233 mg/g. Overall, NAC efficiently adsorbed ACT; thus, it can be considered as an affordable and cost-effective system for the removal of pharmaceutical compounds from aqueous solutions.

“…Recently, several studies have indicated that Fenton oxidation offers an economic alternative for wastewater treatment due to its simplicity and high oxidizing power. For example, effluents containing pesticides, effluents from the pharmaceutical industry and effluents containing phenolic compounds, are treated using this AOP. However, some organic short‐chain acids, such as acetic or oxalic acid, are refractory to Fenton treatment …”

BACKGROUND: This work reports the kinetic and biodegradability analysis of bisphenol A (BPA) Fenton oxidation. An experimental study was carried out within the variables H 2 O 2 /Fe (II)/BPA in the range 10/3/1 to 50/3/1 and at temperatures of 25-70 ∘ C. Kinetics of the environmental parameters dissolved organic carbon (DOC) and chemical oxygen demand (COD) were analysed. RESULTS: The concentration of H 2 O 2 and the temperature have a strong influence on the kinetics of Fenton mineralization of BPA.Working at 70 ∘ C, the measured DOC values matched that calculated using the measured organic acids, which demonstrates that the oxidation reactions proceeded at a sufficient rate to form organic acids. Moreover, as BPA solutions are not easily biodegradable, the biodegradability of the solution during Fenton oxidation was studied by means of respirometry assays, evaluating the short-term biochemical oxygen demand (BOD st )/COD ratio. CONCLUSIONS: The kinetic models proposed are capable of predicting the rate of H 2 O 2 consumption and the oxidation of DOC and COD as a function of the temperature. Under the process conditions tested the treated effluents increased their biodegradability, facilitating compatibility with further biological treatment.
