Journal ArticleDOI

Carbamazepine and diclofenac: removal in wastewater treatment plants and occurrence in water bodies.

TL;DR: The ecotoxicological studies of both drugs imply that they do not easily cause acute toxic effects at their environmental concentrations, however their chronic effects need cautious attention.
Journal ArticleDOI

Selective removal of diclofenac from contaminated water using molecularly imprinted polymer microspheres

TL;DR: MIP had better selectivity and higher adsorption efficiency for DFC as compared to that of powdered activated carbon (PAC) and reusability was demonstrated for at least 12 repeated cycles without significant loss in performance, which is a definite advantage over single-use activated carbon.
Journal ArticleDOI

A comparative study on ozone, hydrogen peroxide and UV based advanced oxidation processes for efficient removal of diethyl phthalate in water.

TL;DR: Heterogeneous catalytic ozonation with Al2O3 was the most effective process for DEP removal and based on pseudo-first-order kinetics at pH7, the studied oxidation processes followed the order.
Journal ArticleDOI

Performance evaluation and application of molecularly imprinted polymer for separation of carbamazepine in aqueous solution.

TL;DR: The CBZ-MIP exhibited a high affinity for CBZ over the competitive compound (Diclofenac) and was more suitable to remove low concentrations of CBZ in large-volume water samples and was in good agreement with corresponding LC-MS/MS data.
Journal ArticleDOI

Catalysed ozonation for removal of an endocrine-disrupting compound using the O3/Fenton reagents system.

TL;DR: The overall reaction rates were significantly enhanced in the O3/Fe2+/H2O2 oxidation system, and allows achieving 100% degradation of DEP (100 mg L−1) in 30 min of reaction time.
