Modification of Structural-Textural Properties of Sulfide Minerals at Polymetallic Concentrate Leaching with Sulfuric Acid and Hydrogen Peroxide Solutions
(Pleiades journals, 2022)
This paper examines the effects of structural-textural characteristics of sulfide minerals on their leaching from polymetallic concentrates with sulfuric acid and hydrogen peroxide solutions. The polymetallic concentrate ...
Oxidized jute as a valuable adsorbent for Congo Red from an aqueous solution
(SAGE Publications Ltd., 2022)
The raw jute fabric was oxidized with 0.2% or 0.4% NaIO4 for 60 or 120 min to obtain valuable adsorbents for the textile dye Congo Red (CR). Batch adsorption experiments were carried out as a function of solution pH, contact ...
Electrochemical stability of gold complex based on mercaptotriazole at optimal condition
(Springer Science and Business Media Deutschland GmbH, 2022)
This study investigates the electrochemical stability of the gold complex based on mercaptotriazole at an optimum pH of nine in the electrolyte with a gold concentration of 2.5 g dm−3. The stability of the complex was ...
Thermodynamic and kinetic analysis of jarosite Pb–Ag sludge thermal decomposition for hydrometallurgical utilization of valuable elements
(Springer Science and Business Media B.V., 2023)
Jarosite is a specific type of hazardous waste determined by the origin of the primary raw materials of the hydrometallurgical process of zinc production. It represents a very demanding raw material for further treatment ...
Studying the influence of common wet processes on the quality of 1 × 1 rib cotton/elastane knitted fabrics
(SAGE Publications Ltd, 2022)
This research studied the influence of common wet processes (i.e. bleaching, dyeing, or softening) on the quality of 1 × 1 rib cotton/elastane knitted fabrics. The changes in their structural (thickness, weight, and stitch ...
Clinoptilolite—An Efficient Carrier for Catalytically Active Nano Oxide Particles
(MDPI, 2023)
Many efforts have been devoted to produce green materials and technology to prevent and minimize the adverse effects on the environment and human health caused primarily by population growth and industrial progress. Over ...
Deep Eutectic Solvent Based Reversed-Phase Dispersive Liquid–Liquid Microextraction and High-Performance Liquid Chromatography for the Determination of Free Tryptophan in Cold-Pressed Oils
(MDPI, 2023)
A fast and straightforward reversed-phase dispersive liquid–liquid microextraction (RP-DLLME) using a deep eutectic solvent (DES) procedure to determine free tryptophan in vegetable oils was developed. The influence of ...
Analysis of the Mechanism of Acid Mine Drainage Neutralization Using Fly Ash as an Alternative Material: A Case Study of the Extremely Acidic Lake Robule in Eastern Serbia
(MDPI, 2022)
Acid mine drainage (AMD) is a waste from mining sites, usually acidic, with high concentrations of sulfates and heavy metal ions. This study investigates the AMD neutralization process using fly ash (FA) as an alternative ...
Sustainable Dyeing and Functionalization of Different Fibers Using Orange Peel Extract’s Antioxidants
(MDPI, 2022)
A diluted ethanol orange peel extract was used for sustainable dyeing and functionalization of different fabrics. The extract analysis was performed using UPLC-ESI-MS/MS; its total flavonoid (0.67 g RE/100 g d.w.) and ...
Steroid-based tracing of sewage-sourced pollution of river water and wastewater treatment efficiency: Dissolved and suspended water phase distribution
(Elsevier B.V., 2022)
In this work, the environmental distribution of steroid compounds and the level of sewage-derived contamination were assessed using sterol ratios in the confluence area of two major rivers in the Serbian capital, where raw ...
