Scientific interest in antimicrobial pollutants, such as ciprofloxacin, has increased. Due to spread of antibiotic-resistant bacteria, resistance genes, and their dissemination the environment. Therefore, remediation is necessary ensure ecological sustainability. The current study aimed optimise removal ciprofloxacin from synthetic water using jamun seed (JS) (Syzygium cumini) biochar a response surface methodology (RSM). Result indicates elimination efficiency ranged between 32.46 94.95%, indicating material can be improved used for organics. residual standard error 4.4% were found predicted model, implying that model credible predict future experimental findings. R-squarred value Langmuir model's R2 0.9681 which inclose agreement with Freundlich isotherm, 0.9757. JS could utilized contaminated wastewater safety

As emerging pollutants, pharmaceutical and personal care products (PPCPs) have received extensive attention due to their high detection frequency (with concentrations ranging from ng/L μg/L) potential risk aqueous environments human health. Advanced oxidation processes (AOPs) are effective techniques for the removal of PPCPs water environments. In AOPs, different types free radicals (HO·, SO4·−, O2·−, etc.) generated decompose into non-toxic small-molecule compounds, finally leading decomposition PPCPs. This review systematically summarizes features various AOPs by radicals. The operation conditions comprehensive performance summarized, reaction mechanisms further revealed. will provide a quick understanding later researchers.

Recently, understanding the origin of induced magnetic characteristics in transition metal atom-doped QDs has been a major focus owing to their potential applications area spintronic devices. A detailed experimental and theoretical investigation was conducted understand physical properties Co-doped ZnS containing different weight percentages Co atoms [CoxZn1-xS (x = 0.00, 0.03, 0.06, 0.09)], prepared using chemical co-precipitation techniques. X-ray diffraction studies proved that all formed an extremely pure cubic zinc blende crystallographic phase free contaminants. The validation quantum dot nature samples provided by HRTEM images, BET studies, blue shift absorption spectra. Both obtained FTIR PL spectra at room temperature also confirmed purity QDs. observed weak ferromagnetic behavior doped due presence p-d hybridization between 3d levels Co2+ ions 3p S2- host Hysteresis loops were validated this nature. These results supported theoretically DFT calculations. FDTD simulations explanation for originating from confinement effect undoped dielectric examined properly, it found grain boundaries contributed effectively providing response. sample more dopants low frequencies showed progressive rise polarisation loss. In addition, are efficient photocatalysts. pH-dependent photodegradation test ciprofloxacin (CIP) antibiotic 9% It nanocatalysts sufficient capability degrade CIP around 94.7% solution pH 10 within one hour. Therefore, besides showing photocatalytic effects, act as ideal dilute semiconductors (DMSs) will undoubtedly become excellent candidates microelectronics industry because special ability exhibit spin-dependent magneto-electro-optical find use spin-polarized light-emitting diodes, solid-state lasers, spin-transistor
