The pseudo-second-order kinetic model
WebbIn essence, pseudo second-order reactions are hugely affected by the amount of adsorbate ions on the adsorbent’s surface and the equilibrium concentration of the adsorbate ions, … Webb29 mars 2024 · The toxicity of organic aerosols has been largely ascribed to the generation of reactive oxygen species, which could subsequently induce oxidative stress in biological systems. The reaction of DTT with redox-active species in PM has been generally assumed to be pseudo-first order, with the oxidative potential of PM being represented by the DTT …
