Analysis of oxygen transport enhancement by functionalized magnetic nanoparticles (FMP) in bioprocesses

A chemical method can be used to perform preliminary experiments for mass tansfer determination[? ? ? ]. This method uses the sodium sulfite oxidation reaction in the presence of Cu2+ or Co2+ catalyst, which is oxidised following the reaction: Na2SO3 + 0.5 O2 Cu 2+ or Co2+ −−−−−−→ Na2SO4 It is possible to determine the absorption of oxygen into a sulfite solution caused by a pseudo-nth-order reaction with the sulfite ions[? ]: OUR = a C∗ O2 − CO2,bulk  √√√√√√√ 2 n + 1knC ∗ O2 DO2,L + k2 L (1)
