The equilibrium and kinetic studies of removal of Pb, Cd, Ni, and Cu metal ions were carried out using activated carbon prepared from palm kernel shell and doped with CeO (Ce/AC). The obtained material carbon was characterized by XRD which showed some crystalline traces of CeO, SEM displaying the porous texture with spherical pores and the determination of pH of point of zero charge (pH) which was found to be equal to 6. The contact time and adsorbate were thoroughly investigated.

Article Synopsis
- * It reveals that the processes of bond breaking and forming are not concerted, and identifies seven stability structural domains (SSD) common across both syn and anti-approach pathways.
- * The research highlights the critical role of N-C triple and C-C double bonds in driving electron flux, leading to structural changes, with the formation of C-C sigma bonds initiating the changes before O-C bonds.

Orange albedo and its adsorption capacity towards bisphenol A (BPA) were studied. Adsorption experiments were conducted in batch mode at 25-55°C. Scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET) and Fourier transform infrared (FTIR) spectroscopy were used to characterise the biosorbent.
