“…Global economic and population growth is currently leading to the troubling reality of the pervasive contamination of freshwater ecosystems. Pharmaceuticals and personal care products (PPCPs), along with other trace organic pollutants, have become pervasive sources of pollution [ 1 , 2 ]. PPCPs are available in a wide range of categories including antibiotics, anti-inflammatory drugs, β-blockers, anticonvulsants, lipid modulators, etc.…”

The long-term presence of PPCPs in the aqueous environment poses a potentially significant threat to human life and physical health and the safety of the water environment. In our previous work, we investigated low-cost pitch-based HCP adsorbents with an excellent adsorption capacity and magnetic responsiveness through a simple one-step Friedel–Crafts reaction. In this work, we further investigated the adsorption behavior of the prepared pitch-based adsorbents onto three PPCP molecules (DFS, AMP, and antipyrine) in detail. The maximum adsorption capacity of P-MPHCP for DFS was 444.93 mg g−1. The adsorption equilibrium and kinetic processes were well described through the Langmuir model and the proposed secondary kinetic model. The negative changes in Gibbs free energy and enthalpy reflected that the adsorption of HCPs onto PPCPs was a spontaneous exothermic process. The recoverability results showed that the adsorption of MPHCP and P-MPHCP onto DFS remained above 95% after 10 adsorption–desorption cycles. The present work further demonstrates that these pitch-based adsorbents can be used for multiple applications, which have a very extensive practical application prospect.

BACKGROUNDIn recent years, advanced oxidation processes (AOP) have gained importance as highly effective methods in the treatment of organic substances with toxic and permanent properties. Diclofenac (DCF) and Triclosan (TCS) pollutants, which are from the endocrine disrupting chemicals (EDCs) that were encountered in various aquatic environments such as inlet and outlet waters of treatment plants, surface waters, drinking water, groundwater and sediments were reported in the literature. In this study, mineralisation of DCF and TCS pollutants, which were the EDCs, were investigated by AOPs. The applied processes were O3, O3/UV, O3/ZnO, UV/ZnO, and O3/UV/ZnO. The studies were carried out at two different initial concentrations (5 and 10 mg/L), at 5 ppm ozone dose, 2 × 8 W UVC light, 0.1 g ZnO, in the original pH, and 30 min reaction time.RESULTSThe highest COD and TOC removal efficiencies were determined in O3/UV/ZnO process as 82% COD, 71% TOC at 5 mg/L concentration for DCF pollutant and as 72% COD, 75% TOC at 10 mg/L concentration for TCS pollutant. For these process conditions, the ozone consumptions were determined 0.13 mgO3/mgCODremoved, 0.31 mgO3/mgTOCremoved and 0.69 mgO3/mgCODremoved, 0.98 mgO3/mgTOCremoved, respectively. The electrical energy per order values were found in the range of 12.33–20.88 kWh/m3 for O3/UV/ZnO processes. Treatment costs of these processes were calculated in the range of 0.002 to 44.823 €/m3.CONCLUSIONFor the treatability of DCF and TCS pollutants, ozone‐based advanced oxidation processes, especially O3/UV/ZnO photocatalytic ozone oxidation process were determined as a feasible process. © 2024 Society of Chemical Industry (SCI).
