In this research, a tungsten oxide was prepared via green (biogenic) synthesis route where sodium tungstate dihydrate and Punica granatum peel extract were used as precursor reducing/capping agent, respectively. The characterization of the performed through various spectroscopic microscopic techniques. results revealed preparation highly crystalline nanorod-shaped (length = 123 nm width 31.3 nm) with probable chemical formula W5O14. Various functional groups on W5O14 surface also reported. nanorods further for removal Bismarck Brown R (BBR) dye from water in batch manner. By varying dose (0.5–3.0 g L−1), BBR solution pH (2−10), contact time (15–120 min), concentration (10–60 mg temperature (30, 40, 50 °C), optimized condition maximum adsorption efficiency measured. that 2.0 L−1 amount to remove ~98% its 10 at 30 °C 7.0 pH. temperature-dependent data fitted different types non-linear isotherm models (e.g., Langmuir Freundlich) assess potential mechanisms relation impacts. synthesized nano-adsorbent fits well Freundlich model capacity 17.84 g−1.

Abstract Organic pollutants negatively impact the environment, including air, water, soil, and living organisms. These come from various sources, industrial, agricultural, domestic activities. Removing organic environment is a difficult task requires combination of prevention innovative strategies. Herein novel nanocomposite consisting beta‐cyclodextrin (β‐CD) modified silver (Ag@β‐CD) gold (Au@‐β‐CD) nanoparticles (NPs) attached on surface Fe 3 O 4 @TiO 2 core–shell structure with an average 530 nm diameter in eco‐friendly presented. In first step, Au@‐β‐CD Ag@‐β‐CD are synthesized, by these nanoparticles. The catalytic activities synthesized investigated for reduction RhB 4‐NP photodegradation MB. composite shows highest performance MB, reactions completed 75, 45 s, 16 min rate constant (k) 0.03 ± 0.005 s −1 , 0.07 0.01 0.25 respectively. follow first‐order law. catalyst reused six cycles after separation reaction system external magnetic field.

One major environmental issue responsible for water pollution is the presence of dyes in aquatic environment as a result human activity, particularly textile industry. Chitosan-Polyvinylpolypyrrolidone (PVPP) polymer composite beads were synthesized and explored adsorption (Bismarck brown (BB), orange G (OG), brilliant blue (BBG), indigo carmine (IC)) from dye solution. The CS-PVPP demonstrated high removal efficiency BB (87%), OG (58%), BBG (42%), IC (49%). reasonable surface area 2.203 m
