Magnetic hexacyanoferrate Cs Low level radioactive

The initial adsorption rate, as t → 0, can be defined as:equation(4)r0=K2Qe2,where Qe is the equilibrium loading of the adsorbent phase in mg/mg, Qt is testes the real-time loading of the adsorbent phase in mg/mg, K2 is the kinetic constant of the pseudo-second-order reaction in mg/(mg·min), t is the contact time in min and r0 is the initial adsorption rate in mg/(mg·min).
