Density functional concept calculations on the communications of the 2,4,5-T molecule with some small silver collections, Ag n with n = 4, 8, and 20, along with extended Ag surfaces, show that the most secure adsorption setup is formed using coordination of Cl9 sites and carbonyl C ═ O team on the 2,4,5-T ligand to the Ag atoms on surfaces. Analyses of charge transfer mechanism and frontier orbitals distributions reveal an electron transfer from 2,4,5-T to the cluster in the ground state, and an inversed fad occurs for the ecstatic singlet state process, consequently causing a chemical enhancement of SERS signals. Considerable calculations aimed out that tiny silver collections, in certain of Ag 20 size, can be used as suitable versions for a metal nanoparticle surface area.

The high voltage straight present electrochemical approach can be control to form plasma on metallic electrodes. Particularly, OH - free radicals that has a high oxidation capacity, so it is feasible to oxidize benzene oring compounds much more effective. The iron electrode is utilized in the studing to combine the liquify procedure of the iron anode electrode with purposes is to create Fe 2+ ions and electrochemical fenton response. Besides, the flocculation process by Fe 2 happen. The plasma will show up with a voltage of 5 kV on the iron electrode in an option of 30 mg/L 2,4-D or 2,4,5 T. After a period time of the response, the aromatic oring compounds contaning the chlorine was treated, the electric conductivity of the solution boosts because of the quantity of Cl - ions launching in the remedy.
