Langmuir, Год журнала: 2024, Номер 40(43), С. 22773 - 22786

Опубликована: Окт. 18, 2024

In the present work, a novel Cu(II) complex containing 10-phenanthroline-5,6-dione (phen-dione) and acetylacetone (acac) was prepared via solid-phase synthesis on silica-modified hercynite magnetic nanoparticles (MNPs). The resulting structure underwent thorough structural analysis using diverse instrumental techniques. catalytic potential of synthesized successfully demonstrated in 2-amino-3-cyano-4

Sustainable Photocatalytic Mitigation of 2-Mercaptobenzothiazole by Expired Medicine Derived Metal-Free Graphitic Carbon Nitride Photocatalyst

ACS ES&T Water, Год журнала: 2024, Номер unknown

2-Mercaptobenzothiazole (MBT) is an emerging pollutant used as accelerator in the rubber industries that has been reported to be toxic for humans, causing respiratory paralysis, cancer, and headache. Also, solid waste created by expired unused medicines environmental concern. Hence, tackle these challenges herein, efficient, sustainable, metal-free photocatalyst synthesized combining medicine metformin with melamine a one-pot system, which effectively degraded MBT. First, it provides solution drugs, second, remediates water pollution caused After well characterization, batch studies were performed revealed EMCN efficiently eliminates 99.6% of MBT within 24 min mineralizes into innocuous products at optimum parameters concentration 20 mg/L, catalyst dosage 10 mg, pH 5. However, only 29% removal was observed CN (graphitic carbon nitride). The statistical (mass: 13.1 pH: 4.6, initial concentration: 21.8 mg/L) degradation derived from ANOVA using Box-Behnken design align closely those studies. Moreover, photodegradation sunlight its recyclability up seven cycles make cost-effective.

study of Using a Phyto-nanosynthesis of Silver and Portulaca Oleracea Plant Extracts in Petroleum Spots Treatment

Journal of Petroleum Research and Studies, Год журнала: 2024, Номер 14(2), С. 138 - 149

Опубликована: Июнь 12, 2024

Petroleum spots has become a major global problem not only in terms of its increase, but also how it is treated, recycled or utilized. It contains suspended and dissolved solids, hydrocarbons many types organic matter heavy metals. The reuse petroleum faces the removing pollutant compounds before discharging them into any natural stream. this study, nano –coagulant material was used their efficiency turbidity, Total Organic Carbon (TOC) Chemical Oxygen Demand (COD) from were compared. study conducted laboratories Ecology Sciences Department, University Kufa, Iraq 2022. By synthesizing Phyto-nanosilver as Phyto-nano silver Leaves Portulaca oleracea plant extracts to reduce turbidity pollutants spots. Jar test experiments showed that 0.5 mg / L dose can remove 95.5 % (COD), 87.3% TOC 85.2 turbidity. Also, removal P. 1 mg/L removed COD content 91.9%, 87.5 82.4% respectively Moreover, when using nano-sliver only, TOC, COD, would reach 75.3%, 80.4%, 81.3 %, respectively. results research materials treating depositing without harming environment.
