The magnetic PMADETA/PDVB IPNs has a very large equilibrium adsorption capacity towards salicylic acid, and it can be easily magnetically separated by a magnet, and hence its dynamic adsorption is expected. The dynamic adsorption of salicylic AZD 8055 on the magnetic PMADETA/PDVB IPNs was investigated and the results are depicted in Fig. 5. It shows that the shape of the dynamic adsorption curve is very sharp, indicating that the adsorption of salicylic acid on the magnetic PMADETA/PDVB IPNs reaches equilibrium quickly after leakage.

We defined C/C0 = 0.05 (where C is the concentration of salicylic acid from the effluent, mg/L) as the breakthrough point and C/C0 = 0.95 as the saturated point, and the volume of the effluent to reach the breakthrough point and the saturated point is defined as Vb and Vs, respectively. Fig. 5 indicates that the Vb is 102.3 BV (1 BV = 10 mL) and Vc is 147.1 BV at an initial concentration of 1037.9 mg/L and a flow rate of 1.3 mL/min, and the corresponding breakthrough and saturated adsorption capacities can be calculated to be 105.6 and 119.9 mg/mL for the wet magnetic PMADETA/PDVB IPNs, respectively.
