The surface charge is one of the important parameter that controls the type of adsorbate to get absorb. To fulfil this EHop-016 demand, Zeta potential analysis was performed for both the BN nanomaterials. By definition Zeta potential is the potential difference between the dispersion medium and the stationary phase of the medium attached to the dispersed particles. The values of the zeta potential reveal the type and value of charge on the dispersed particles. For BN nanomaterials, the medium was kept water at natural pH. A constant voltage (3.4 V) was applied between the electrodes placed in the dispersion medium and conductivities of both the BN nanomaterials were measured that was found to be 0.114 mS/cm and 0.123 mS/cm for BN nanoparticles and BN nanosheets respectively. From spleen zeta potential values were evaluated that are −37.6 mV and −59.0 mV for BN nanoparticles and BN nanosheets respectively. The negative values of the zeta potential demonstrate the presence of negative charge on their surface.
