Characterization of magnetic latex particles: Experimental.

The super-paramagnetic properties of dried samples of the prepared magnetic colloidal particles were assessed by magnetization measurements which performed by using vibrating sample magnetometer (VSM) located in CNRS-IRC, Villeurbanne. Magnetization behavior of the driedmagnetic particles was followed by decreasing strength of the applied magnetic field from 21 to 0 kOe, at room temperature.

Characterization of the magnetic adsorbents: Results and discussion.

Fig. SS1: Magnetization curveof MPDVB.

As clearly seen from magnetization versus magnetic field in figure 4, no reduced remanence and coercivity being zero were detected, indicating that MPDVB are superparamagnetic(Yu-Ting Zhou et al. 2009). This is due to the superparamagnetic character of the used magnetic emulsion as seed. The saturation magnetization of the MPDVB is 49.5emu/g, which are higher than or comparable to other magnetic adsorbents.The magnetic alginate adsorbent prepared by Agnès Bée et al. 2011 showed a saturation magnetization about of 32.2 emu/g.D. Harikishore Kumar Reddy and Seung-Mok Lee. 2013reported in a review on magnetic chitosan composites that the saturation magnetization values for various MCCs varied between 9 and 62 emu/g.Chen Yuwei et al 2011,Jiu-Hua Deng et al. 2013have obtained a magnetic graphene oxide nanocomposite adsorbent with a saturation magnetization value of 31.8 emu/g. MPDVB with Their high saturation magnetization and superparamagnetic properties could be easily and rapidly separated by any external magnetic field,and could be possibly reusable without aggregation after removing the external magnetic field (Yu-Ting Zhou et al. 2009,Yan-Ru Zhang et al. 2013, Yulei Tai et al. 2011).
