The variables of initial concentration, time, pH...

This research examined the genotoxic activity in the seawater of Asin Bay (Gulf of Gulluk) located in Mugla, Turkey, Aegean coast of Turkey. Genotoxic activities of 66 raw samples, taken from 17 different stations in the spring and summer seasons of the year 2013, were determined by using in vitro...

The importance of anaerobic ammonium oxidation (anammox) – a metabolic pathway that can generate dinitrogen – remains poorly understood in freshwater river system. Using the 15N-isotope pairing technique (15N IPT) combined with membrane inlet mass spectrometry (MIMS), the potential rates of...

The activated charcoal (AC) was synthesized from banana leaf rim (BLR) through three activation methods; physical (BLRC), chemical (Z BLRC, zinc chloride) and microwave activation (MW BLRC). The AC was characterized using fourier transform infrared spectrometer (FT-IR), Thermogravimetric analysis...

One of the fundamental carotenoid compounds available in microalga Chlorella pyrenoidosa is lutein, which is a commercially valuable antioxidant compound. The extraction of lutein from C. pyrenoidosa was studied in detail under various operating conditions. Acid pretreatment was done using 10% HCl...

In this study, it was studied various advanced oxidation treatment processes; Fenton, UV/H2O2, UV/O3/H2O2 for treatability of hospital wastewaters containing antibiotics (cephalosporines). Taguchi’s L25 orthogonal array design was applied to design of advanced oxidation processes, for simplification...

Photocatalytic abatement of o-xylene was investigated by immobilized ZnO on granular activated carbon (ZnO/GAC) under UV irradiation. Immobilization of ZnO increased the breakthrough time and removal capacity by 51 and 57%, respectively, in optimal conditions. The catalytic potential of the ZnO/GAC...

To evaluate the effects of titanium and bio-fertilizers on some agronomic and physiological properties of triticale grown in cadmium (Cd) contaminated soil, a glasshouse experiment was conducted based on a completely randomized design with three replications. The treatments were arranged in a 4×4...
