(PAL-SeNPs) leaf wastes by green synthesis method. The characteristic structure of PAL-SeNPs was determined by UV-vis spectroscopy, X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), scanning electron microscope (SEM), energy dispersive X-ray (EDX), fourier transform infrared spectroscopy (FTIR), thermogravimetry-differential thermal analysis (TGA-DTA), dynamic light scattering (DLS), zetasizer, and point of zero charge (pHpzc). The effects of pH, adsorbent amount, time, initial concentration, and temperature were investigated by batch adsorption studies. 2 different kinetic and 4 isotherm models were tested and error analysis functions were determined for the most suitable model. Accordingly, the particle size, crystallinity, pHpzc value and average surface charge of PAL-SeNPs were determined as 9.969 nm, 48.50 %, 3.47, and -23.6 mV, respectively. Also, the most suitable kinetic and isotherm models for the removal of CR dye with PAL-SeNPs were found as Pseudo-second-order and Freundlich, with R2 values of 0.996, respectively. Also, where the optimum pH was 7.00, the maximum adsorption capacity was calculated as 96.59 mgCR/gPAL-SeNPs. The results obtained show that environmentally friendly and low-cost PAL-SeNPs produced by the green synthesis method are a suitable alternative for the removal of CR dye.en10.1002/slct.202403106info:eu-repo/semantics/closedAccessGreen SynthesisCongo RedNanoparticleAdsorptionPrunus Armeniaca L.Article937Q3Q3WOS:0013258801000012-s2.0-852055646352
