The widespread usage of 2,4-Dichlorophenoxyacetic acid (2,4-D) as an herbicide has led to alarming levels environmental pollution, presenting severe risks ecosystems and human health. This study aimed synthesize a new adsorbent, activated carbon from candle bush pods (CBAC) via low-temperature phosphoric activation investigate its ability for adsorptive elimination 2,4-D. setup adsorption system requires the experimental determination isotherms their thorough modeling, which is achieved through advanced statistical physics models (ASPMs). characterization CBAC revealed porous morphology with remarkable specific surface area (415.31 m2/g). XRD graphitic structures, while XPS detected phosphate groups, oxygen-containing functional groups. Double layer single energy (DLSE) model – one ASPMs both non-parallel parallel orientation 2,4-D molecules on CBAC, saturation capacity values increasing temperature (up 252.35 mg/g) at pH 2. was physisorption (ΔE = 12.62–16.26 kJ/mol) spontaneous endothermic. Hence, findings herein demonstrate potential sustainable effective adsorbent mitigating pollution caused by

Cr(vi) is a heavy metal with high toxicity level. Many levels of in the environment are above established quality standards. The membrane filtration method technique that can be used to reduce because it more effective and efficient compared other methods. In this research, ability PES integrated boehmite nanoparticles coated polyphenolic compounds from Samanea saman bark extract (mixed matrix hollow fiber PES/B-polyphenol) was studied reducing levels. removal carried out research module, so test conditions were obtained similar actual conditions. XRD, FTIR, PSA, tensile strength, SEM-EDS characterization study characteristics nanofiller. XRD diffractogram shows specific peak for at 2θ = 14°. results FTIR B-polyphenols also identified presence Al-O functional groups wave numbers 733, 603, 474 cm-1 nanofillers OH, C[double bond, length as m-dash]C, C-O, m-dash]O PES/B-polyphenol membranes. Based on strength tests, observed Young's modulus value 56.67 MPa had porous surface evenly distributed. Mixed PES/B-polyphenols have been fabricated up 92.12%. water flux 14.1 L m-2 h-1 porosity 85.3% contact angle formed between 58-32°. obtained, mixed has potential applied larger scale regarding its application
