Phenanthrene, a prime polycyclic aromatic hydrocarbon (PAH) pollutant, is utilized to develop nanoporous hypercrosslinked polymeric adsorbent (poly-PHEN-C) through the microwave-assisted process from catalyst anhydrous AlCl3 and solvent CHCl3. Nanoporous poly-PHEN-C proves be highly effective for adsorbing CO2 flue gas removing organic dyes wastewater. capture capacity of 3.2 mmol g–1 at 298 K 1 bar ascribed combined effect surface area (1472 m2 g–1), micropores (1.1, 1.7 nm), pore volume (0.73 cm3 π electrons. The separation selectivity mixture, i.e., CO2/N2 (15:85), estimated ideal adsorbed solution theory model. Moreover, employed removal cationic (crystal violet, CV) anionic (alizarin red S, ARS) aqueous solutions. In batch process, it exhibits adsorption capacities 161 mg CV 120 ARS. continuous fixed-bed column breakthrough 300 achieved CV. Thus, present study offers an eco-friendly approach effectively managing three categories hazardous pollutants, namely, PAHs, greenhouse CO2, dyes, sustainable strategy environmental management.

A heteroatom (nitrogen and phosphorus) enriched pyridinic bridged inorganic-organic hybrid material (HPHM) was synthesized by polycondensing phosphonitrilic chloride trimer (PNC) 2,6-diaminopyridine in DMSO at 140 °C. The used as an efficient electrode for the electrochemical detection of selenium(iv) ions [Se(iv)] aqueous solution. HPHM (active mass loading 4.1 mg cm-2) achieves a range 5-50 ppb deposition potential -1.2 V time 170 s with lower limit (LOD) 2.18 ppb. This LOD is significantly below World Health Organization's (WHO) recommended maximum level selenium drinking water. Moreover, maintains high selectivity Se(iv) presence various interfering sensitivity over 200 cycles only minimal (∼6.83%) decline current density response. higher ion capability attributed to strategic incorporation nitrogen phosphorus heteroatoms, enhancing material's properties.
