In water treatment, the application of advanced oxidation processes (AOPs) which involve generation not only hydroxyl but also sulfate radicals has recently attracted increasing attention worldwide.

Biochar undergoes significant transformations in soil as a result of chemical, physical, and biological processes. These alterations can impact its initial properties, influencing both agronomic effectiveness capacity for carbon sequestration. Long-term observations biochar aging effects are limited but highly relevant, they provide more realistic picture the societal benefits than short-term studies with relatively “fresh” biochar. This study aimed to describe their on...

Arsenic and heavy metal contamination in water presents serious environmental public health challenges, requiring effective treatment technologies. Titanium dioxide (TiO2) nanoparticles offer promising adsorption potential due to their high surface area, mesoporosity, chemical stability. This study investigates the removal of As(V), Cd(II), Cu(II), Pb(II) by TiO2 under environmentally relevant conditions (pH 3 7), commonly encountered industrial natural waters. was characterized using SEM,...

This work explores the relationship between water quality and public trust in their supply, an arsenic-affected region of Serbia. The results from online survey are presented subjected to Pearson’s correlation, cluster analysis, principal component analysis. In general, respondents settlements with known arsenic issues had a poor opinion on tap water. was underlined by consumption bottled water, more than 43% responders purchasing at least 5 L week. addition great economic cost, relatively...

Polluted sediments with organic pollutants like PAHs represent a potential danger to environment, human health and obstacle water management. Removal of polluted sediment provides the for reuse nutrients from sediment, crop production or materials in building industry. The purpose this study was determine efficacy using hard wood biochar immobilization bioaccessible polycyclic aromatic hydrocarbons (PAHs) historically sediment. main question is would carbon materials' presence (in case...

The role of microplastics (MPs) on the fate and transport various pollutants in water matrices is major concern, but it still relatively under investigated. In order to consider conditions real aquatic environments, changes polyethylene (PE) structure during fabrication microplastic particles for specific uses should not be neglected. Thus, this work considers isolated PE from two types personal care products, which are possible sources contamination environments. adsorption affinity these...

Soil deterioration due to excessive fertilization and climate change has adverse effects on crop growth globally. In order enhance soil fertility, application of organic amendments gained importance. One them represents biochar which is recognized as a sustainable agricultural practice with significant benefits for health it bolsters enhances nutrient retention structure while sequestering carbon long-time scale. However, during aging been shown its properties. Knowledge about those...

This study investigates how soil enriched with carbon-rich materials, such as biochar, influences the sorption and biodegradation capabilities of organophosphorus pesticides (Fenthion, Fenitrothion, Parathion Methyl) under nonequilibrium conditions. Additionally, experiments were conducted to enhance potential biochar from Miscanthus×giganteus by introducing bacteria capable degrading (OPPs). Transport carried out in stainless-steel columns (4 cm diameter, 20 length) filled amended...

The subject of this study was to investigate the adsorption behavior selected divalent metals (Cu (II), Cd Pb (II)) on amino-functionalized multiwalled carbon nanotubes, MWCNT-NH2, at four pH values (3; 4.5, 6, 11), in order estimate possibility using MWCNT-NH2 remove ion metal from aqueous solutions relatively low concentrations (0.01-0.1 mg L-1). focus determine mechanism experimental conditions. ions best described by pseudo-second kinetics model, which indicates that can be attributed...

Polycyclic aromatic hydrocarbons (PAHs) belong to the persistent organic pollutant class and are ubiquitously present in environment. As a consequence of their high hydrophobicity, PAHs aquatic environments tend rapidly sink down bottom sediments which most important reservoirs This paper presents validation further performance evaluation method modified in-house for PAHs’ sample preparation analysis sediment using gas chromatography-mass spectrometry (GC-MS). The covers determining...

Increased pesticide uses over the last few decades raise a serious threat to environment, especially groundwater most important drinking water resource. This work investigates biodegradation potential of two selected organophosphorus pesticides, OPPs (fenthion and disulfoton) on Danube alluvial sediment in presence microbially inoculated biochar (BC). The investigated BC was produced by slow pyrolysis Miscanthus giganteus at temperature 400°C. Bacillus megaterium BD5 isolated from...

The aim of this study was to investigate the transport behavior two selected organophosphorus pesticides (chlorpyrifos-CP and chlorpyrifos-methyl-CPM) through Danube alluvial sediment in absence presence microbially inoculated chars originated from sugar beet shreds (biochar produced at 400°C three hydrochars 180, 200, 220°C). Bacillus megaterium strain used for microbial inoculation investigated carbon-based adsorbents. Column experiments were simulate sorption...

This work presents results from a pilot-scale drinking water treatment plant used to investigate the performance of ozone oxidation and granulated activated carbon (GAC) adsorption in removing natural organic matter (NOM) specific micropollutants groundwater. The investigated groundwater has relatively low NOM content (1.83?1.01 mg C/L total carbon, TOC). Using gas chromatography/mass spectrometry (GC/MS) screening analysis, variety different compounds were identified, including...

<p>Amendment of alluvial sediments with carbon rich materials such as biochars can be an effective method for controlling the penetration hazardous substances from river water into drinking sources during bank filtration (RBF). In this work, transport chlorinated phenols (CPs) simulated RBF through Danube sediment and without biochar amendment was studied. order to assess effect on CPs retention in sediment, column experiments were carried out, addition biocide exclude...
