Kinetics considerations concerning the oxidative degradation by photo-fenton process of some antibiotics
Environmental Engineering and Management Journal › Vol. 9 › Nr. 1 Abstract
The aim of this study is the evaluation of photo-Fenton as a suitable advanced oxidation process to degrade ampicillin and streptomycin antibiotics. The degradation was studied by monitoring the organic substrate concentration changes in aqueous solution as a function of reaction time using COD analysis. The oxidation process follows two successive stages. In the first stage (I) the oxidation of the antibiotics takes place with high reaction rate, leading to intermediate oxidation pr...

Environmental Engineering and Management Journal › Vol. 13 › Nr. 12 Abstract
In this study, the COD removal of Azithromycin from synthetic wastewater (produced to have a composition similar to industrial
wastewater) using a Fenton-like (Fe°/H2O2) system in combination with coagulation has been investigated. Chemical oxygen
demand (COD) was selected as the main parameter to assess treatment efficacy in the current study (COD° = 390mg/Lequivalent
to 200mg/LAzithromycin). First, the coagulation process was carried out on the synthetic wastewater and the... Autori: Ahmad Reza Yazdanbakhsh ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26586
EQUILIBRUM AND KINETIC STUDIES ON THE ADSORPTION OF PENICILLIN G BY CHESTNUT SHELL

THERMOPHLIC COMPOSTING PERFORMANCE OF PIG MANURE SPIKEDWITH CARBADOX
Environmental Engineering and Management Journal › Vol. 15 › Nr. 10 Carbadox is a veterinary antibiotic and widely used in livestock production as feed additives. Carbadox and its metabolites have the potential of provoking a tumor-inducing mutation. In this study, the influence of carbadox addition on composting performance and its removal during thermophilic composting were investigated. The results showed that the carbadox addition slightly influenced pH variation and C/N ratio, and also improved the decomposition of organic matter. However, XRD analysis indi...

EFFECTS OF CHLORTETRACYCLINE AND COOPER ON SWINE MANURE ANAEROBIC DIGESTION
Environmental Engineering and Management Journal › Vol. 17 › Nr. 12 Chlortetracycline (CTC) and copper (Cu) are simultaneously used as feed additives to improve the growth performance and to prevent infection in pig farming. After ingestion by animals, most of these compounds are excreted and coexist in swine manure. They might have an influence on anaerobic digestion when the swine manure is used as substrate in a biogas plant. The purpose of this study was to investigate the effects of both CTC and Cu on batch swine manure anaerobic digestion in order to bette...
