The current research aimed to simultaneously generate sulfate and hydroxyl radicals to break down Acid Black ATT dye. It was observed that using UV radiation and ozonation separately is insufficient for the complete decomposition of this dye compound. Based on the results, the UV/O3/PMS process is able to completely remove all dye concentrations under the optimum conditions (pH=10, O3=20 mg/min, PMS=0.4 mM L-1, and AB-ATT=20 mg/L) in 10 minutes, with significant removal of TOC and COD. For every 0.1 mM increase in PMS concentration, dye removal increased by 14 %. Hydroxyl and sulfate radicals were identified as the primary active species responsible for the degradation. The degradation followed first kinetic order, and hydroxylation and decarboxylation pathways were found to contribute significantly to the process. Therefore, the combined UV/O3/PMS process can be used as an environmentally friendly hybrid technology of advanced sulfate-based oxidation to remove recalcitrant contaminants from aqueous solutions.

The present study was designed and conducted to simultaneously produce two sulfate and hydroxyl radicals for the decomposition of Acid Black ATT dye, which showed that UV radiation and ozonation alone cannot decompose and break down this dye compound completely. The UV/O3/PMS process is able to completely remove all dye concentrations from 10 to 30 mg / L in 10 minutes. Then, the effect of parameters such as contact time, pH, initial dye concentrations, different doses of persulfate, and ozone under ultraviolet radiation on dye removal was studied. Based on the results of this experiment, the optimal concentrations of variables include pH, ozone concentration, and persulfate concentration, and initial dye concentration includes 10, 20 mg /min, 0.4 mM L− 1, and 20 mg/ L, respectively. For every 0.1 mM increase in PMS concentration, the amount of dye removal increased by 14%. Based on the findings of this study, the combined UV/O3/PMS process can be concluded that the environmentally friendly hybrid technology of advanced sulfate-based oxidation removes contaminants resistant to aqueous media.

“…On the other hand, the rare element Ru is known to be toxic. It has been widely used in multiple applications including fuel cells, diesel fuel production, azo dye degradation, catalytic dehydrogenations, and so on. − It is critical to examine the nanotoxicity of Ru or RuO 2 NPs-based commercial products in depth, given the expanding applications and use of these materials. So far, no comprehensive research into the nanotoxicity of Ru or RuO 2 NPs has been conducted.…”

In this review, ruthenium nanoparticles (Ru NPs)-based functional nanomaterials have attractive electrocatalytic characteristics and they offer considerable potential in a number of fields. Ru-based binary or multimetallic NPs are widely utilized for electrode modification because of their unique electrocatalytic properties, enhanced surface-area-to-volume ratio, and synergistic effect between two metals provides as an effective improved electrode sensor. This perspective review suggests the current research and development of Ru-based nanomaterials as a platform for electrochemical (EC) sensing of harmful substances, biomolecules, insecticides, pharmaceuticals, and environmental pollutants. The advantages and limitations of mono-, bi-, and multimetallic Rubased nanocomposites for EC sensors are discussed. Besides, the relevant EC properties and analyte sensing approaches are also presented. On the basis of these insights, we highlighted recent results for synthesizing techniques and EC environmental pollutant sensors from the perspectives of diverse supports, including graphene, carbon nanotubes, silica, semiconductors, metal sulfides, and polymers. Finally, this work overviews the modern improvements in the utilization of Ru-based nanocomposites on the basis for electroanalytical sensors as well as suggestions for the field's future development.
