Modification of glassy carbon nanoparticles using titanium nanoparticles as a platform for determining diclofenac sodium

This article presents an investigation on the behavior of a chemically modified glassy carbon electrode as a sensing platform for the detection of Diclofenac Sodium. The study also explores the potential application of this electrode in analyzing real samples, including blood, urine, and wastewater. In addition, the synthesis of Titanium Nanoparticles and filaments used in the electrode modification was carried out using a novel method developed by our research group. This unique combination of materials has significantly enhanced the novelty of the technology, as no previous studies have reported such a combination

Analysis of trace amounts of estrogenic compounds in high volume water samples by SPE-UPLC-MS/MS

In this work, a solid phase extraction (SPE) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and optimized for the simultaneous analysis of six different estrogenic compounds in water. The developed method is suitable for the determination of the selected compounds at the low ng/L level. Real environmental water samples will be analyzed using this method

Examination of whey de-fatting by enhanced membrane filtration

The largest quantities of by-products of dairy processing originates from the cheese making. Whey proteins are used for animal feeding and human nutrition as well, for example in dry soups, infant formulas, and supplements. The fat components of the whey might impair its use. The aim of our experiments was to investigate the separation of the lipid fraction of whey. The microfiltration is said to be a gentle and energy efficient method for this task. During the measurements 0.2 μm microfiltration membranes were used and the membrane separation was enhanced by vibration, inserting static mixer and air sparging. The de-fatting efficiency, the retention of the whey components, the flux values, and the resistances in different combinations were compared in this paper

Survey of Sars-Cov-2 Genetic Material Reduction During a Traditional Wastewater Treatment Technology

The transmission of Severe Acute Respiratory Syndrome Coronavirus-2 in a community can be monitored by a wastewater-based epidemiological approach due to fecal shedding. Although sewage surveillance has gained a considerable amount of attention over the last 16 months, an indirect issue within the topic is whether traditional wastewater treatment technologies are sufficiently efficient to eliminate the genetic material of SARS-CoV-2. Samples were taken from the Wastewater Treatment Plant in Nagykanizsa before the virus was concentrated, nucleic acid extracted and SARS-CoV-2 detected by RT-qPCR (Quantitative reverse transcription PCR). The influent and primary treated samples tested positive, while after the secondary treatment, all the results were negative. Consequently, the activated sludge process proved to be efficient in terms of the removal of SARS-CoV-2
