Abstract Ibuprofen is a potential environmental toxin and carcinogen for freshwater ecosystems, posing significant risks to human health, particularly through its impact on kidney function. This research introduced new type of bismuth ferrite perovskite material, modified with separable lanthanum, explore how sunlight can be used break down ibuprofen in water. The catalysts the study were created green synthesis co-precipitation methods, their characteristics analyzed using various techniques like X-ray diffractometry (XRD), Field Scanning emission microscopy (FE-SEM), photoelectron spectroscopy(XPS), UV-VIS absorption spectroscopy(UV-DRS) Photoluminescence spectra(PL). explored effect photocatalysis degradation.

In this study, a new composite adsorbent consisting of aluminum-modified activated carbon (abbreviated hereafter AC@Al) was synthesized for the removal Ibuprofen compound (IBU), non-steroidal anti-inflammatory drug (NSAID). Coconut shells were used as source material carbon, which then modified with AlCl3 to improve its properties. Adsorbent dosage, pH and initial IBU concentration, well contact time temperature, are some factors affecting adsorption that investigated in work. Specifically, at 2.0 ± 0.1 application 0.5 g/L AC@Al 100 mg/L IBU, more than 90% removed, reaching 100% addition 1.0 adsorbent. The kinetic data followed pseudo-second-order model.
