The textile and clothing industry is one of the most resource-intensive and polluting industries. The circular economy (CE) is one of the solutions to these problems. The textile industry has been identified as one of the most in need of transformation towards CE. The transition to a circular economy requires changes in the behavior and actions of...

Plastics have recently become an indispensable part of everyone’s daily life due to their versatility, durability, light weight, and low production costs. The increasing production and use of plastics poses great environmental problems due to their incomplete utilization, a very long period of biodegradation, and a negative impact on living organis...

Plastics have recently become an indispensable part of everyone's daily life due to their versatility, durability, light weight and low production costs. The increasing production and use of plastics poses a great danger due to the very long period of degradation, but also the negative impact on living organisms. Decomposing plastics lead to the fo...

Differential pulse and cyclic voltammetry were used to investigate the electrocatalytic effects of two oxygen-containing graphene derivatives, as surface modifiers, on the oxidation mechanism of acemetacin (ACM), a non-steroidal anti-inflammatory drug. Scanning electron microscopy was employed to examine the modified electrodes surfaces, showing th...

Creosote, a mixture of polycyclic aromatic hydrocarbons (PAHs), was and is a wood impregnate of widespread use. Over the years the accumulation of creosote PAHs in soils and freshwaters has increased, causing a threat to ecosystems. The combined ozonation-biodegradation process is proposed to improve the slow and inefficient biodegradation of creos...

The present paper describes the effect of the concentration of two graphene oxides (with different oxygen content) in the modifier layer on the electrochemical and structural properties of noble metal disk electrodes used as working electrodes in voltammetry. The chemistry of graphene oxides was tested using EDS, FTIR, UV–Vis spectroscopy, and comb...

This paper discusses the electrochemical behavior of antiviral drug Tenofovir (TFV) and its possible applicability towards electroanalytical determination with diverse detection strategies using square-wave voltammetry. Namely, oxidation processes were investigated using glassy carbon electrode with graphene oxide surface modification (GO/GCE), whi...

The stability of cellulose phosphates(III) and cellulose phosphates(V) in suspensions in 2 M potassium hydroxide solutions in the temperature range of 25–80 °C were investigated. The release of phosphorus compounds in eluates was determined by ³¹P NMR using methyl phosphonic acid (potassium methyl phosphonate) as internal standard.

As anticoagulants, rivaroxaban (RIV) and dabigatran etexilate (DAB) are high-risk drugs that can cause life-threatening bleeding. They are a group of drugs that require optimal dosing, therefore their monitoring in the patient is of great importance, especially in emergencies. In this study, we developed a rapid, sensitive square-wave voltammetric...

A sensitive square‐wave voltammetry (SWV) method based on basal‐plane pyrolytic graphite electrode (BPPGE) and edge‐plane pyrolytic graphite electrode (EPPGE) was developed to determine the concentration of the pesticide mandipropamid (MAN) in spiked river water and grape juice samples. Under optimal experimental conditions, the SWV response of EPP...

In this study, a simple and sensitive square wave voltammetric procedure has been developed for the determination of acemetacin (ACM) on graphite flake paste electrode (GFPE) and glassy carbon electrode (GCE). Under optimized conditions, the dependence of ACM peak current on its concentration showed wide linear range: 0.03 – 1.0 μmol L−1 and 0.7 –...

In this paper, the fabrication, surface characterisation and electrochemical properties of graphite flake (GFPE) and multilayer graphene (MLGPE) paste electrodes are described. The Raman investigations and scanning electron microscopy were used to analyze and compare structure of both carbon materials. The electroanalytical performance of both elec...

In this study, the development of an electroanalytical assay based on square wave voltammetry technique for determining sesamol (Ses) in sesame oil samples is described. The influence of various factors such as pH of the supporting electrolyte, its composition, and SW (square wave) parameters was studied. Linearity of the peak current depended on t...

Oxidation and reduction processes of the insecticide fenthion was comparatively investigated at a reduced graphene oxide modified glassy carbon electrode (RGO-GCE) and a cyclic renewable silver amalgam film electrode (Hg(Ag)FE) using square wave stripping voltammetry (SWSV).
