This study aimed to understand the adsorption process of cephalexin (CPX) from aqueous solution by a biochar produced fiber residue palm oil. Scanning electron microscopy, Fourier transform infrared spectroscopy, Boehm titration, and point zero charge were used characterize morphology surface functional groups adsorbent. Batch tests carried out evaluate effects pH, temperature, antibiotic structure. The behavior followed Langmuir model pseudo-second-order with maximum CPX capacity 57.47 mg...
The photodegradation of chlorothalonil, a polychlorinated aromatic fungicide widely used in agriculture, was investigated under ultraviolet–visible irradiation the presence and absence different humic substances that significantly enhance chlorothalonil phototransformation. On basis kinetic model, an analytical study, effect scavengers, phosphorescence measurement, varying conditions, it possible to demonstrate this accelerating is due their capacity reduce triplet state via H-donor reaction...
ABSTRACT The contamination of wastewater with pharmaceutical compounds represents a growing environmental challenge due to the inefficiency conventional treatment systems in removing these emerging contaminants. coffee husk (CH) is promising bioadsorbent its abundant availability as byproduct production. This study focuses on using untreated CH an adsorbent for acetaminophen (ACE) and ciprofloxacin (CIP) while exploring impact pyrolysis temperature adsorption efficiency compounds. results...
This work considered the sonochemical degradation (using a bath-type reactor, at 375 kHz and 106.3 W L-1, 250 mL of sample) three representative halogenated pharmaceuticals (cloxacillin, diclofenac, losartan) in urine matrices. The action route process was initially established. Then, selectivity system, to degrade target simulated fresh compared with electrochemical oxidation BDD anode, 1.88 mA cm-2), UVC/H2O2 (at 60 light 500 mol L-1 H2O2). Also, treatment cloxacillin an actual sample by...
Pristine pyrogenic carbonaceous material (BRH) obtained from rice husk and modified with FeCl3 (BRH-FeCl3) were prepared explored as carbocatalysts for the activation of peroxymonosulfate (PMS) to degrade a model pharmaceutical (acetaminophen, ACE) in water. The BRH-FeCl3/PMS system removed faster than BRH/PMS. This is explained because BRH-FeCl3, compared BRH, modification (iron played role structuring agent mainly) increased average pore diameter presence functional groups such -COO-,...
Antibiotics elimination by some photochemical processes involves ferric ions, but little is discussed about the fundamental aspects of complexation effects on their degradation. This study compares photodegradation two fluoroquinolones, three β-lactams, and complexes in deionized water. The complexed antibiotics were more recalcitrant than free to solar light action (the rate constants diminished 50%). To better photodegradation, other experiments considering representative cases...
Persistent Organic Pollutants (POPs) in water can reach levels below ppt (ng L−1), representing a challenge for risk assessment using long-term exposure. Therefore, sampling devices to monitor trace of organic compounds are suitable due their sensitivity and low detection limits. In this work, the field calibration monitoring POPs, such as Polycyclic Aromatic Hydrocarbons (PAHs) pesticides, drinking reservoir were carried out semipermeable membrane (SPMDs). The SPMDs spiked with deuterated...
Sensitizers are being used to improve the photocatalytic activity of semiconductors in visible light region solar spectrum. Different types dyes reported as sensitizer agents, such ruthenium complex molecules, porphyrins and Pt complexes, which critically assessed because they hazardous substance. Therefore, it is necessary replace these compounds with safer like organic dyes. This work evaluated degradation diclofenac using two different (Perinaphtenone Eosin-Y) agents. The catalyst...
Los antibióticos son fármacos relevantes para el tratamiento de enfermedades infecciosas en humanos y animales origen microbiano, estas sustancias frecuentemente encontradas ambiente, sobre cual ejercen un impacto negativo.
